Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539718, here are decompositions:
- 5 + 31539713 = 31539718
- 11 + 31539707 = 31539718
- 47 + 31539671 = 31539718
- 59 + 31539659 = 31539718
- 131 + 31539587 = 31539718
- 149 + 31539569 = 31539718
- 251 + 31539467 = 31539718
- 317 + 31539401 = 31539718
Showing the first eight; more decompositions exist.
