Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77750, here are decompositions:
- 3 + 77747 = 77750
- 7 + 77743 = 77750
- 19 + 77731 = 77750
- 31 + 77719 = 77750
- 37 + 77713 = 77750
- 61 + 77689 = 77750
- 103 + 77647 = 77750
- 109 + 77641 = 77750
Showing the first eight; more decompositions exist.
