Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77748, here are decompositions:
- 5 + 77743 = 77748
- 17 + 77731 = 77748
- 29 + 77719 = 77748
- 37 + 77711 = 77748
- 59 + 77689 = 77748
- 61 + 77687 = 77748
- 67 + 77681 = 77748
- 89 + 77659 = 77748
Showing the first eight; more decompositions exist.
