Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 146644, here are decompositions:
- 5 + 146639 = 146644
- 41 + 146603 = 146644
- 101 + 146543 = 146644
- 131 + 146513 = 146644
- 167 + 146477 = 146644
- 227 + 146417 = 146644
- 263 + 146381 = 146644
- 347 + 146297 = 146644
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 146,644 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 146644 first appears in π at position 890,722 of the decimal expansion (the 890,722ordinal-suffix:nd 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.
