Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500406, here are decompositions:

13 + 500393 = 500406
17 + 500389 = 500406
37 + 500369 = 500406
43 + 500363 = 500406
73 + 500333 = 500406
89 + 500317 = 500406
107 + 500299 = 500406
149 + 500257 = 500406

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 500,406 and was likely granted around 1893.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 500406 first appears in π at position 538,100 of the decimal expansion (the 538,100ordinal-suffix:th digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
