Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42732, here are decompositions:
- 5 + 42727 = 42732
- 13 + 42719 = 42732
- 23 + 42709 = 42732
- 29 + 42703 = 42732
- 31 + 42701 = 42732
- 43 + 42689 = 42732
- 83 + 42649 = 42732
- 89 + 42643 = 42732
Showing the first eight; more decompositions exist.
