Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64238, here are decompositions:
- 7 + 64231 = 64238
- 67 + 64171 = 64238
- 157 + 64081 = 64238
- 241 + 63997 = 64238
- 331 + 63907 = 64238
- 337 + 63901 = 64238
- 397 + 63841 = 64238
- 439 + 63799 = 64238
Showing the first eight; more decompositions exist.
