Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601718, here are decompositions:

  • 7 + 31601711 = 31601718
  • 11 + 31601707 = 31601718
  • 19 + 31601699 = 31601718
  • 47 + 31601671 = 31601718
  • 67 + 31601651 = 31601718
  • 89 + 31601629 = 31601718
  • 149 + 31601569 = 31601718
  • 151 + 31601567 = 31601718

Showing the first eight; more decompositions exist.
