Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468794, here are decompositions:
- 17 + 31468777 = 31468794
- 37 + 31468757 = 31468794
- 67 + 31468727 = 31468794
- 127 + 31468667 = 31468794
- 157 + 31468637 = 31468794
- 163 + 31468631 = 31468794
- 197 + 31468597 = 31468794
- 223 + 31468571 = 31468794
Showing the first eight; more decompositions exist.
