Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72944, here are decompositions:
- 7 + 72937 = 72944
- 13 + 72931 = 72944
- 37 + 72907 = 72944
- 43 + 72901 = 72944
- 61 + 72883 = 72944
- 73 + 72871 = 72944
- 127 + 72817 = 72944
- 181 + 72763 = 72944
Showing the first eight; more decompositions exist.
