Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707020, here are decompositions:

  • 13 + 8707007 = 8707020
  • 17 + 8707003 = 8707020
  • 37 + 8706983 = 8707020
  • 41 + 8706979 = 8707020
  • 53 + 8706967 = 8707020
  • 59 + 8706961 = 8707020
  • 67 + 8706953 = 8707020
  • 73 + 8706947 = 8707020

Showing the first eight; more decompositions exist.
