Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77930, here are decompositions:
- 31 + 77899 = 77930
- 37 + 77893 = 77930
- 67 + 77863 = 77930
- 157 + 77773 = 77930
- 199 + 77731 = 77930
- 211 + 77719 = 77930
- 241 + 77689 = 77930
- 271 + 77659 = 77930
Showing the first eight; more decompositions exist.
