Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55680, here are decompositions:
- 7 + 55673 = 55680
- 13 + 55667 = 55680
- 17 + 55663 = 55680
- 19 + 55661 = 55680
- 41 + 55639 = 55680
- 47 + 55633 = 55680
- 59 + 55621 = 55680
- 61 + 55619 = 55680
Showing the first eight; more decompositions exist.
