Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461608, here are decompositions:
- 37 + 31461571 = 31461608
- 127 + 31461481 = 31461608
- 151 + 31461457 = 31461608
- 181 + 31461427 = 31461608
- 307 + 31461301 = 31461608
- 379 + 31461229 = 31461608
- 571 + 31461037 = 31461608
- 601 + 31461007 = 31461608
Showing the first eight; more decompositions exist.
