Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660090, here are decompositions:

  • 3 + 8660087 = 8660090
  • 13 + 8660077 = 8660090
  • 37 + 8660053 = 8660090
  • 151 + 8659939 = 8660090
  • 163 + 8659927 = 8660090
  • 181 + 8659909 = 8660090
  • 223 + 8659867 = 8660090
  • 349 + 8659741 = 8660090

Showing the first eight; more decompositions exist.
