Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77770, here are decompositions:
- 23 + 77747 = 77770
- 47 + 77723 = 77770
- 59 + 77711 = 77770
- 71 + 77699 = 77770
- 83 + 77687 = 77770
- 89 + 77681 = 77770
- 149 + 77621 = 77770
- 179 + 77591 = 77770
Showing the first eight; more decompositions exist.
