Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 63816, here are decompositions:
- 7 + 63809 = 63816
- 13 + 63803 = 63816
- 17 + 63799 = 63816
- 23 + 63793 = 63816
- 43 + 63773 = 63816
- 73 + 63743 = 63816
- 79 + 63737 = 63816
- 89 + 63727 = 63816
Showing the first eight; more decompositions exist.
