Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77786, here are decompositions:
- 3 + 77783 = 77786
- 13 + 77773 = 77786
- 43 + 77743 = 77786
- 67 + 77719 = 77786
- 73 + 77713 = 77786
- 97 + 77689 = 77786
- 127 + 77659 = 77786
- 139 + 77647 = 77786
Showing the first eight; more decompositions exist.
