Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40790, here are decompositions:
- 3 + 40787 = 40790
- 19 + 40771 = 40790
- 31 + 40759 = 40790
- 97 + 40693 = 40790
- 151 + 40639 = 40790
- 163 + 40627 = 40790
- 181 + 40609 = 40790
- 193 + 40597 = 40790
Showing the first eight; more decompositions exist.
