Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123600, here are decompositions:

7 + 123593 = 123600
17 + 123583 = 123600
19 + 123581 = 123600
47 + 123553 = 123600
53 + 123547 = 123600
73 + 123527 = 123600
83 + 123517 = 123600
97 + 123503 = 123600

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 123,600 and was likely granted around 1871.

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

Position in π

The digit sequence 123600 first appears in π at position 780,503 of the decimal expansion (the 780,503ordinal-suffix:rd 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.
