Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537944, here are decompositions:
- 5 + 31537939 = 31537944
- 23 + 31537921 = 31537944
- 41 + 31537903 = 31537944
- 73 + 31537871 = 31537944
- 83 + 31537861 = 31537944
- 101 + 31537843 = 31537944
- 107 + 31537837 = 31537944
- 197 + 31537747 = 31537944
Showing the first eight; more decompositions exist.
