Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64290, here are decompositions:
- 7 + 64283 = 64290
- 11 + 64279 = 64290
- 19 + 64271 = 64290
- 53 + 64237 = 64290
- 59 + 64231 = 64290
- 67 + 64223 = 64290
- 73 + 64217 = 64290
- 101 + 64189 = 64290
Showing the first eight; more decompositions exist.
