Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666130, here are decompositions:

  • 37 + 8666093 = 8666130
  • 61 + 8666069 = 8666130
  • 71 + 8666059 = 8666130
  • 73 + 8666057 = 8666130
  • 79 + 8666051 = 8666130
  • 103 + 8666027 = 8666130
  • 107 + 8666023 = 8666130
  • 113 + 8666017 = 8666130

Showing the first eight; more decompositions exist.
