Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139126, here are decompositions:
- 3 + 139123 = 139126
- 5 + 139121 = 139126
- 17 + 139109 = 139126
- 47 + 139079 = 139126
- 59 + 139067 = 139126
- 149 + 138977 = 139126
- 167 + 138959 = 139126
- 227 + 138899 = 139126
Showing the first eight; more decompositions exist.
