Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475792, here are decompositions:

  • 13 + 31475779 = 31475792
  • 43 + 31475749 = 31475792
  • 79 + 31475713 = 31475792
  • 109 + 31475683 = 31475792
  • 181 + 31475611 = 31475792
  • 193 + 31475599 = 31475792
  • 211 + 31475581 = 31475792
  • 349 + 31475443 = 31475792

Showing the first eight; more decompositions exist.
