Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545962, here are decompositions:

  • 3 + 31545959 = 31545962
  • 43 + 31545919 = 31545962
  • 61 + 31545901 = 31545962
  • 103 + 31545859 = 31545962
  • 199 + 31545763 = 31545962
  • 223 + 31545739 = 31545962
  • 463 + 31545499 = 31545962
  • 523 + 31545439 = 31545962

Showing the first eight; more decompositions exist.
