Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 63216, here are decompositions:
- 5 + 63211 = 63216
- 17 + 63199 = 63216
- 19 + 63197 = 63216
- 37 + 63179 = 63216
- 67 + 63149 = 63216
- 89 + 63127 = 63216
- 103 + 63113 = 63216
- 113 + 63103 = 63216
Showing the first eight; more decompositions exist.
