Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100928, here are decompositions:
- 127 + 100801 = 100928
- 181 + 100747 = 100928
- 229 + 100699 = 100928
- 307 + 100621 = 100928
- 337 + 100591 = 100928
- 379 + 100549 = 100928
- 409 + 100519 = 100928
- 571 + 100357 = 100928
Showing the first eight; more decompositions exist.
