Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64244, here are decompositions:
- 7 + 64237 = 64244
- 13 + 64231 = 64244
- 73 + 64171 = 64244
- 163 + 64081 = 64244
- 181 + 64063 = 64244
- 211 + 64033 = 64244
- 331 + 63913 = 64244
- 337 + 63907 = 64244
Showing the first eight; more decompositions exist.
