Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539934, here are decompositions:

  • 3 + 31539931 = 31539934
  • 71 + 31539863 = 31539934
  • 113 + 31539821 = 31539934
  • 197 + 31539737 = 31539934
  • 227 + 31539707 = 31539934
  • 263 + 31539671 = 31539934
  • 347 + 31539587 = 31539934
  • 467 + 31539467 = 31539934

Showing the first eight; more decompositions exist.
