Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 32688, here are decompositions:
- 41 + 32647 = 32688
- 67 + 32621 = 32688
- 79 + 32609 = 32688
- 101 + 32587 = 32688
- 109 + 32579 = 32688
- 127 + 32561 = 32688
- 151 + 32537 = 32688
- 157 + 32531 = 32688
Showing the first eight; more decompositions exist.
