Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77912, here are decompositions:
- 13 + 77899 = 77912
- 19 + 77893 = 77912
- 73 + 77839 = 77912
- 139 + 77773 = 77912
- 151 + 77761 = 77912
- 181 + 77731 = 77912
- 193 + 77719 = 77912
- 199 + 77713 = 77912
Showing the first eight; more decompositions exist.
