Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539394, here are decompositions:
- 17 + 31539377 = 31539394
- 41 + 31539353 = 31539394
- 251 + 31539143 = 31539394
- 311 + 31539083 = 31539394
- 347 + 31539047 = 31539394
- 443 + 31538951 = 31539394
- 587 + 31538807 = 31539394
- 641 + 31538753 = 31539394
Showing the first eight; more decompositions exist.
