Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 63688, here are decompositions:
- 17 + 63671 = 63688
- 29 + 63659 = 63688
- 41 + 63647 = 63688
- 59 + 63629 = 63688
- 71 + 63617 = 63688
- 89 + 63599 = 63688
- 101 + 63587 = 63688
- 167 + 63521 = 63688
Showing the first eight; more decompositions exist.
