Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 946440, here are decompositions:
- 23 + 946417 = 946440
- 29 + 946411 = 946440
- 43 + 946397 = 946440
- 71 + 946369 = 946440
- 73 + 946367 = 946440
- 109 + 946331 = 946440
- 113 + 946327 = 946440
- 149 + 946291 = 946440
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 946,440 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 946440 first appears in π at position 548,469 of the decimal expansion (the 548,469ordinal-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.
