Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465936, here are decompositions:
- 107 + 31465829 = 31465936
- 179 + 31465757 = 31465936
- 239 + 31465697 = 31465936
- 263 + 31465673 = 31465936
- 317 + 31465619 = 31465936
- 389 + 31465547 = 31465936
- 647 + 31465289 = 31465936
- 743 + 31465193 = 31465936
Showing the first eight; more decompositions exist.
