Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536442, here are decompositions:

  • 59 + 31536383 = 31536442
  • 83 + 31536359 = 31536442
  • 89 + 31536353 = 31536442
  • 149 + 31536293 = 31536442
  • 239 + 31536203 = 31536442
  • 281 + 31536161 = 31536442
  • 389 + 31536053 = 31536442
  • 461 + 31535981 = 31536442

Showing the first eight; more decompositions exist.
