Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31490698, here are decompositions:

  • 11 + 31490687 = 31490698
  • 47 + 31490651 = 31490698
  • 89 + 31490609 = 31490698
  • 131 + 31490567 = 31490698
  • 191 + 31490507 = 31490698
  • 251 + 31490447 = 31490698
  • 347 + 31490351 = 31490698
  • 359 + 31490339 = 31490698

Showing the first eight; more decompositions exist.
