Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535928, here are decompositions:
- 19 + 31535909 = 31535928
- 97 + 31535831 = 31535928
- 101 + 31535827 = 31535928
- 107 + 31535821 = 31535928
- 131 + 31535797 = 31535928
- 181 + 31535747 = 31535928
- 211 + 31535717 = 31535928
- 257 + 31535671 = 31535928
Showing the first eight; more decompositions exist.
