Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564186, here are decompositions:
- 23 + 31564163 = 31564186
- 29 + 31564157 = 31564186
- 47 + 31564139 = 31564186
- 53 + 31564133 = 31564186
- 83 + 31564103 = 31564186
- 107 + 31564079 = 31564186
- 197 + 31563989 = 31564186
- 233 + 31563953 = 31564186
Showing the first eight; more decompositions exist.
