Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615200, here are decompositions:

  • 3 + 8615197 = 8615200
  • 23 + 8615177 = 8615200
  • 101 + 8615099 = 8615200
  • 137 + 8615063 = 8615200
  • 149 + 8615051 = 8615200
  • 227 + 8614973 = 8615200
  • 233 + 8614967 = 8615200
  • 311 + 8614889 = 8615200

Showing the first eight; more decompositions exist.
