Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77122, here are decompositions:
- 29 + 77093 = 77122
- 41 + 77081 = 77122
- 53 + 77069 = 77122
- 131 + 76991 = 77122
- 173 + 76949 = 77122
- 179 + 76943 = 77122
- 239 + 76883 = 77122
- 251 + 76871 = 77122
Showing the first eight; more decompositions exist.
