Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522848, here are decompositions:

  • 101 + 31522747 = 31522848
  • 131 + 31522717 = 31522848
  • 179 + 31522669 = 31522848
  • 191 + 31522657 = 31522848
  • 251 + 31522597 = 31522848
  • 257 + 31522591 = 31522848
  • 307 + 31522541 = 31522848
  • 389 + 31522459 = 31522848

Showing the first eight; more decompositions exist.
