Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464960, here are decompositions:
- 13 + 31464947 = 31464960
- 19 + 31464941 = 31464960
- 139 + 31464821 = 31464960
- 151 + 31464809 = 31464960
- 173 + 31464787 = 31464960
- 179 + 31464781 = 31464960
- 229 + 31464731 = 31464960
- 251 + 31464709 = 31464960
Showing the first eight; more decompositions exist.
