Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64472, here are decompositions:
- 19 + 64453 = 64472
- 73 + 64399 = 64472
- 139 + 64333 = 64472
- 193 + 64279 = 64472
- 241 + 64231 = 64472
- 283 + 64189 = 64472
- 349 + 64123 = 64472
- 409 + 64063 = 64472
Showing the first eight; more decompositions exist.
