Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139098, here are decompositions:
- 7 + 139091 = 139098
- 19 + 139079 = 139098
- 31 + 139067 = 139098
- 131 + 138967 = 139098
- 139 + 138959 = 139098
- 181 + 138917 = 139098
- 199 + 138899 = 139098
- 229 + 138869 = 139098
Showing the first eight; more decompositions exist.
