Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147404586, here are decompositions:

  • 3 + 2147404583 = 2147404586
  • 7 + 2147404579 = 2147404586
  • 97 + 2147404489 = 2147404586
  • 139 + 2147404447 = 2147404586
  • 157 + 2147404429 = 2147404586
  • 193 + 2147404393 = 2147404586
  • 277 + 2147404309 = 2147404586
  • 433 + 2147404153 = 2147404586

Showing the first eight; more decompositions exist.
