Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539106, here are decompositions:

  • 17 + 31539089 = 31539106
  • 23 + 31539083 = 31539106
  • 59 + 31539047 = 31539106
  • 317 + 31538789 = 31539106
  • 353 + 31538753 = 31539106
  • 617 + 31538489 = 31539106
  • 773 + 31538333 = 31539106
  • 953 + 31538153 = 31539106

Showing the first eight; more decompositions exist.
