Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604664, here are decompositions:
- 17 + 31604647 = 31604664
- 23 + 31604641 = 31604664
- 37 + 31604627 = 31604664
- 53 + 31604611 = 31604664
- 61 + 31604603 = 31604664
- 103 + 31604561 = 31604664
- 107 + 31604557 = 31604664
- 131 + 31604533 = 31604664
Showing the first eight; more decompositions exist.
