Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64972, here are decompositions:
- 3 + 64969 = 64972
- 53 + 64919 = 64972
- 71 + 64901 = 64972
- 101 + 64871 = 64972
- 179 + 64793 = 64972
- 191 + 64781 = 64972
- 263 + 64709 = 64972
- 293 + 64679 = 64972
Showing the first eight; more decompositions exist.
