Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67784, here are decompositions:
- 7 + 67777 = 67784
- 43 + 67741 = 67784
- 61 + 67723 = 67784
- 307 + 67477 = 67784
- 331 + 67453 = 67784
- 337 + 67447 = 67784
- 373 + 67411 = 67784
- 523 + 67261 = 67784
Showing the first eight; more decompositions exist.
