Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 146646, here are decompositions:
- 7 + 146639 = 146646
- 29 + 146617 = 146646
- 37 + 146609 = 146646
- 43 + 146603 = 146646
- 83 + 146563 = 146646
- 103 + 146543 = 146646
- 107 + 146539 = 146646
- 127 + 146519 = 146646
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 146,646 and was likely granted around 1873.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 146646 first appears in π at position 243,305 of the decimal expansion (the 243,305ordinal-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.
