Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475876, here are decompositions:

  • 79 + 31475797 = 31475876
  • 97 + 31475779 = 31475876
  • 127 + 31475749 = 31475876
  • 163 + 31475713 = 31475876
  • 193 + 31475683 = 31475876
  • 199 + 31475677 = 31475876
  • 277 + 31475599 = 31475876
  • 433 + 31475443 = 31475876

Showing the first eight; more decompositions exist.
