Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139342, here are decompositions:
- 3 + 139339 = 139342
- 29 + 139313 = 139342
- 41 + 139301 = 139342
- 101 + 139241 = 139342
- 173 + 139169 = 139342
- 233 + 139109 = 139342
- 251 + 139091 = 139342
- 263 + 139079 = 139342
Showing the first eight; more decompositions exist.
