Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611242, here are decompositions:

  • 79 + 31611163 = 31611242
  • 193 + 31611049 = 31611242
  • 199 + 31611043 = 31611242
  • 331 + 31610911 = 31611242
  • 349 + 31610893 = 31611242
  • 463 + 31610779 = 31611242
  • 601 + 31610641 = 31611242
  • 613 + 31610629 = 31611242

Showing the first eight; more decompositions exist.
