Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18732, here are decompositions:
- 13 + 18719 = 18732
- 19 + 18713 = 18732
- 31 + 18701 = 18732
- 41 + 18691 = 18732
- 53 + 18679 = 18732
- 61 + 18671 = 18732
- 71 + 18661 = 18732
- 139 + 18593 = 18732
Showing the first eight; more decompositions exist.
