Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77784, here are decompositions:
- 11 + 77773 = 77784
- 23 + 77761 = 77784
- 37 + 77747 = 77784
- 41 + 77743 = 77784
- 53 + 77731 = 77784
- 61 + 77723 = 77784
- 71 + 77713 = 77784
- 73 + 77711 = 77784
Showing the first eight; more decompositions exist.
