Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465264, here are decompositions:
- 41 + 31465223 = 31465264
- 71 + 31465193 = 31465264
- 317 + 31464947 = 31465264
- 443 + 31464821 = 31465264
- 563 + 31464701 = 31465264
- 647 + 31464617 = 31465264
- 683 + 31464581 = 31465264
- 821 + 31464443 = 31465264
Showing the first eight; more decompositions exist.
