Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604, here are decompositions:
- 3 + 31601 = 31604
- 31 + 31573 = 31604
- 37 + 31567 = 31604
- 61 + 31543 = 31604
- 73 + 31531 = 31604
- 127 + 31477 = 31604
- 211 + 31393 = 31604
- 271 + 31333 = 31604
Showing the first eight; more decompositions exist.
