Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001072, here are decompositions:
- 3 + 1001069 = 1001072
- 31 + 1001041 = 1001072
- 73 + 1000999 = 1001072
- 103 + 1000969 = 1001072
- 151 + 1000921 = 1001072
- 211 + 1000861 = 1001072
- 223 + 1000849 = 1001072
- 349 + 1000723 = 1001072
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 1,001,072 and was likely granted around 1911.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
