Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540096, here are decompositions:

  • 83 + 31540013 = 31540096
  • 89 + 31540007 = 31540096
  • 233 + 31539863 = 31540096
  • 239 + 31539857 = 31540096
  • 257 + 31539839 = 31540096
  • 359 + 31539737 = 31540096
  • 383 + 31539713 = 31540096
  • 389 + 31539707 = 31540096

Showing the first eight; more decompositions exist.
