Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 63664, here are decompositions:
- 5 + 63659 = 63664
- 17 + 63647 = 63664
- 47 + 63617 = 63664
- 53 + 63611 = 63664
- 131 + 63533 = 63664
- 137 + 63527 = 63664
- 191 + 63473 = 63664
- 197 + 63467 = 63664
Showing the first eight; more decompositions exist.
