Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15944, here are decompositions:
- 7 + 15937 = 15944
- 31 + 15913 = 15944
- 37 + 15907 = 15944
- 43 + 15901 = 15944
- 67 + 15877 = 15944
- 127 + 15817 = 15944
- 157 + 15787 = 15944
- 211 + 15733 = 15944
Showing the first eight; more decompositions exist.
