Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139174, here are decompositions:
- 5 + 139169 = 139174
- 41 + 139133 = 139174
- 53 + 139121 = 139174
- 83 + 139091 = 139174
- 107 + 139067 = 139174
- 197 + 138977 = 139174
- 251 + 138923 = 139174
- 257 + 138917 = 139174
Showing the first eight; more decompositions exist.
