Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577396, here are decompositions:
- 3 + 31577393 = 31577396
- 7 + 31577389 = 31577396
- 13 + 31577383 = 31577396
- 43 + 31577353 = 31577396
- 73 + 31577323 = 31577396
- 127 + 31577269 = 31577396
- 157 + 31577239 = 31577396
- 163 + 31577233 = 31577396
Showing the first eight; more decompositions exist.
