Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462532, here are decompositions:

  • 61 + 31462471 = 31462532
  • 151 + 31462381 = 31462532
  • 181 + 31462351 = 31462532
  • 193 + 31462339 = 31462532
  • 463 + 31462069 = 31462532
  • 571 + 31461961 = 31462532
  • 613 + 31461919 = 31462532
  • 691 + 31461841 = 31462532

Showing the first eight; more decompositions exist.
