Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145946, here are decompositions:
- 13 + 145933 = 145946
- 43 + 145903 = 145946
- 67 + 145879 = 145946
- 127 + 145819 = 145946
- 139 + 145807 = 145946
- 193 + 145753 = 145946
- 223 + 145723 = 145946
- 313 + 145633 = 145946
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 145,946 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 145946 first appears in π at position 461,357 of the decimal expansion (the 461,357ordinal-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.
