Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501646, here are decompositions:
- 23 + 501623 = 501646
- 29 + 501617 = 501646
- 53 + 501593 = 501646
- 83 + 501563 = 501646
- 227 + 501419 = 501646
- 263 + 501383 = 501646
- 347 + 501299 = 501646
- 359 + 501287 = 501646
Showing the first eight; more decompositions exist.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 501,646 and was likely granted around 1893.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 501646 first appears in π at position 484,604 of the decimal expansion (the 484,604ordinal-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.
