Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526770, here are decompositions:

  • 17 + 31526753 = 31526770
  • 47 + 31526723 = 31526770
  • 101 + 31526669 = 31526770
  • 137 + 31526633 = 31526770
  • 167 + 31526603 = 31526770
  • 281 + 31526489 = 31526770
  • 293 + 31526477 = 31526770
  • 347 + 31526423 = 31526770

Showing the first eight; more decompositions exist.
