Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77228, here are decompositions:
- 37 + 77191 = 77228
- 61 + 77167 = 77228
- 127 + 77101 = 77228
- 181 + 77047 = 77228
- 199 + 77029 = 77228
- 211 + 77017 = 77228
- 397 + 76831 = 77228
- 409 + 76819 = 77228
Showing the first eight; more decompositions exist.
