Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78784, here are decompositions:
- 3 + 78781 = 78784
- 5 + 78779 = 78784
- 47 + 78737 = 78784
- 71 + 78713 = 78784
- 131 + 78653 = 78784
- 191 + 78593 = 78784
- 317 + 78467 = 78784
- 347 + 78437 = 78784
Showing the first eight; more decompositions exist.
