Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 36640, here are decompositions:
- 3 + 36637 = 36640
- 11 + 36629 = 36640
- 41 + 36599 = 36640
- 53 + 36587 = 36640
- 89 + 36551 = 36640
- 113 + 36527 = 36640
- 167 + 36473 = 36640
- 173 + 36467 = 36640
Showing the first eight; more decompositions exist.
