Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458924, here are decompositions:

  • 11 + 31458913 = 31458924
  • 17 + 31458907 = 31458924
  • 23 + 31458901 = 31458924
  • 61 + 31458863 = 31458924
  • 103 + 31458821 = 31458924
  • 127 + 31458797 = 31458924
  • 137 + 31458787 = 31458924
  • 163 + 31458761 = 31458924

Showing the first eight; more decompositions exist.
