Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139118, here are decompositions:
- 97 + 139021 = 139118
- 151 + 138967 = 139118
- 181 + 138937 = 139118
- 229 + 138889 = 139118
- 277 + 138841 = 139118
- 379 + 138739 = 139118
- 439 + 138679 = 139118
- 457 + 138661 = 139118
Showing the first eight; more decompositions exist.
