Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77040, here are decompositions:
- 11 + 77029 = 77040
- 17 + 77023 = 77040
- 23 + 77017 = 77040
- 37 + 77003 = 77040
- 79 + 76961 = 77040
- 97 + 76943 = 77040
- 127 + 76913 = 77040
- 157 + 76883 = 77040
Showing the first eight; more decompositions exist.
