Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77812, here are decompositions:
- 11 + 77801 = 77812
- 29 + 77783 = 77812
- 89 + 77723 = 77812
- 101 + 77711 = 77812
- 113 + 77699 = 77812
- 131 + 77681 = 77812
- 191 + 77621 = 77812
- 239 + 77573 = 77812
Showing the first eight; more decompositions exist.
