Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021358, here are decompositions:
- 31 + 1021327 = 1021358
- 61 + 1021297 = 1021358
- 67 + 1021291 = 1021358
- 97 + 1021261 = 1021358
- 199 + 1021159 = 1021358
- 229 + 1021129 = 1021358
- 271 + 1021087 = 1021358
- 277 + 1021081 = 1021358
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 1,021,358 and was likely granted around 1912.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
