Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72064, here are decompositions:
- 11 + 72053 = 72064
- 17 + 72047 = 72064
- 71 + 71993 = 72064
- 101 + 71963 = 72064
- 131 + 71933 = 72064
- 197 + 71867 = 72064
- 227 + 71837 = 72064
- 257 + 71807 = 72064
Showing the first eight; more decompositions exist.
