Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586534, here are decompositions:

  • 37 + 31586497 = 31586534
  • 61 + 31586473 = 31586534
  • 73 + 31586461 = 31586534
  • 127 + 31586407 = 31586534
  • 157 + 31586377 = 31586534
  • 223 + 31586311 = 31586534
  • 277 + 31586257 = 31586534
  • 433 + 31586101 = 31586534

Showing the first eight; more decompositions exist.
