Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535904, here are decompositions:
- 73 + 31535831 = 31535904
- 83 + 31535821 = 31535904
- 107 + 31535797 = 31535904
- 151 + 31535753 = 31535904
- 157 + 31535747 = 31535904
- 163 + 31535741 = 31535904
- 223 + 31535681 = 31535904
- 233 + 31535671 = 31535904
Showing the first eight; more decompositions exist.
