Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101644, here are decompositions:
- 3 + 101641 = 101644
- 17 + 101627 = 101644
- 41 + 101603 = 101644
- 71 + 101573 = 101644
- 83 + 101561 = 101644
- 107 + 101537 = 101644
- 113 + 101531 = 101644
- 131 + 101513 = 101644
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 101,644 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
