Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139074, here are decompositions:
- 7 + 139067 = 139074
- 41 + 139033 = 139074
- 53 + 139021 = 139074
- 97 + 138977 = 139074
- 107 + 138967 = 139074
- 137 + 138937 = 139074
- 151 + 138923 = 139074
- 157 + 138917 = 139074
Showing the first eight; more decompositions exist.
