Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1000272, here are decompositions:
- 19 + 1000253 = 1000272
- 23 + 1000249 = 1000272
- 41 + 1000231 = 1000272
- 59 + 1000213 = 1000272
- 61 + 1000211 = 1000272
- 73 + 1000199 = 1000272
- 79 + 1000193 = 1000272
- 89 + 1000183 = 1000272
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 1,000,272 and was likely granted around 1911.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
