Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 940680, here are decompositions:
- 11 + 940669 = 940680
- 31 + 940649 = 940680
- 61 + 940619 = 940680
- 73 + 940607 = 940680
- 107 + 940573 = 940680
- 127 + 940553 = 940680
- 131 + 940549 = 940680
- 137 + 940543 = 940680
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 940,680 and was likely granted around 1909.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 940680 first appears in π at position 895,774 of the decimal expansion (the 895,774ordinal-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.
