Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77908, here are decompositions:
- 41 + 77867 = 77908
- 59 + 77849 = 77908
- 107 + 77801 = 77908
- 197 + 77711 = 77908
- 227 + 77681 = 77908
- 317 + 77591 = 77908
- 359 + 77549 = 77908
- 419 + 77489 = 77908
Showing the first eight; more decompositions exist.
