Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139792, here are decompositions:
- 5 + 139787 = 139792
- 53 + 139739 = 139792
- 71 + 139721 = 139792
- 83 + 139709 = 139792
- 89 + 139703 = 139792
- 131 + 139661 = 139792
- 173 + 139619 = 139792
- 281 + 139511 = 139792
Showing the first eight; more decompositions exist.
