Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583200, here are decompositions:
- 29 + 31583171 = 31583200
- 41 + 31583159 = 31583200
- 53 + 31583147 = 31583200
- 113 + 31583087 = 31583200
- 149 + 31583051 = 31583200
- 167 + 31583033 = 31583200
- 239 + 31582961 = 31583200
- 251 + 31582949 = 31583200
Showing the first eight; more decompositions exist.
