Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 74784, here are decompositions:
- 5 + 74779 = 74784
- 13 + 74771 = 74784
- 23 + 74761 = 74784
- 37 + 74747 = 74784
- 53 + 74731 = 74784
- 67 + 74717 = 74784
- 71 + 74713 = 74784
- 97 + 74687 = 74784
Showing the first eight; more decompositions exist.
