Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101722, here are decompositions:
- 3 + 101719 = 101722
- 29 + 101693 = 101722
- 41 + 101681 = 101722
- 59 + 101663 = 101722
- 149 + 101573 = 101722
- 191 + 101531 = 101722
- 233 + 101489 = 101722
- 239 + 101483 = 101722
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 101,722 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
