Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139192, here are decompositions:
- 5 + 139187 = 139192
- 23 + 139169 = 139192
- 59 + 139133 = 139192
- 71 + 139121 = 139192
- 83 + 139109 = 139192
- 101 + 139091 = 139192
- 113 + 139079 = 139192
- 233 + 138959 = 139192
Showing the first eight; more decompositions exist.
