Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72894, here are decompositions:
- 5 + 72889 = 72894
- 11 + 72883 = 72894
- 23 + 72871 = 72894
- 71 + 72823 = 72894
- 97 + 72797 = 72894
- 127 + 72767 = 72894
- 131 + 72763 = 72894
- 167 + 72727 = 72894
Showing the first eight; more decompositions exist.
