Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535552, here are decompositions:

  • 3 + 31535549 = 31535552
  • 211 + 31535341 = 31535552
  • 241 + 31535311 = 31535552
  • 379 + 31535173 = 31535552
  • 409 + 31535143 = 31535552
  • 421 + 31535131 = 31535552
  • 439 + 31535113 = 31535552
  • 541 + 31535011 = 31535552

Showing the first eight; more decompositions exist.
