Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31505592, here are decompositions:

  • 23 + 31505569 = 31505592
  • 59 + 31505533 = 31505592
  • 71 + 31505521 = 31505592
  • 73 + 31505519 = 31505592
  • 103 + 31505489 = 31505592
  • 149 + 31505443 = 31505592
  • 211 + 31505381 = 31505592
  • 233 + 31505359 = 31505592

Showing the first eight; more decompositions exist.
