Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516184, here are decompositions:
- 31 + 31516153 = 31516184
- 61 + 31516123 = 31516184
- 97 + 31516087 = 31516184
- 103 + 31516081 = 31516184
- 157 + 31516027 = 31516184
- 163 + 31516021 = 31516184
- 421 + 31515763 = 31516184
- 487 + 31515697 = 31516184
Showing the first eight; more decompositions exist.
