Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64090, here are decompositions:
- 23 + 64067 = 64090
- 53 + 64037 = 64090
- 71 + 64019 = 64090
- 83 + 64007 = 64090
- 113 + 63977 = 64090
- 227 + 63863 = 64090
- 233 + 63857 = 64090
- 251 + 63839 = 64090
Showing the first eight; more decompositions exist.
