Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526862, here are decompositions:

  • 43 + 31526819 = 31526862
  • 53 + 31526809 = 31526862
  • 71 + 31526791 = 31526862
  • 89 + 31526773 = 31526862
  • 109 + 31526753 = 31526862
  • 113 + 31526749 = 31526862
  • 131 + 31526731 = 31526862
  • 139 + 31526723 = 31526862

Showing the first eight; more decompositions exist.
