Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586162, here are decompositions:

  • 31 + 31586131 = 31586162
  • 61 + 31586101 = 31586162
  • 103 + 31586059 = 31586162
  • 109 + 31586053 = 31586162
  • 199 + 31585963 = 31586162
  • 313 + 31585849 = 31586162
  • 379 + 31585783 = 31586162
  • 499 + 31585663 = 31586162

Showing the first eight; more decompositions exist.
