Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464840, here are decompositions:
- 13 + 31464827 = 31464840
- 19 + 31464821 = 31464840
- 31 + 31464809 = 31464840
- 53 + 31464787 = 31464840
- 59 + 31464781 = 31464840
- 83 + 31464757 = 31464840
- 109 + 31464731 = 31464840
- 131 + 31464709 = 31464840
Showing the first eight; more decompositions exist.
