Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535952, here are decompositions:
- 5 + 31535947 = 31535952
- 11 + 31535941 = 31535952
- 13 + 31535939 = 31535952
- 43 + 31535909 = 31535952
- 73 + 31535879 = 31535952
- 131 + 31535821 = 31535952
- 199 + 31535753 = 31535952
- 211 + 31535741 = 31535952
Showing the first eight; more decompositions exist.
