Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77120, here are decompositions:
- 19 + 77101 = 77120
- 73 + 77047 = 77120
- 79 + 77041 = 77120
- 97 + 77023 = 77120
- 103 + 77017 = 77120
- 157 + 76963 = 77120
- 283 + 76837 = 77120
- 349 + 76771 = 77120
Showing the first eight; more decompositions exist.
