Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468800, here are decompositions:
- 7 + 31468793 = 31468800
- 23 + 31468777 = 31468800
- 43 + 31468757 = 31468800
- 73 + 31468727 = 31468800
- 101 + 31468699 = 31468800
- 163 + 31468637 = 31468800
- 211 + 31468589 = 31468800
- 227 + 31468573 = 31468800
Showing the first eight; more decompositions exist.
