Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615018, here are decompositions:

  • 31 + 8614987 = 8615018
  • 67 + 8614951 = 8615018
  • 79 + 8614939 = 8615018
  • 151 + 8614867 = 8615018
  • 229 + 8614789 = 8615018
  • 241 + 8614777 = 8615018
  • 337 + 8614681 = 8615018
  • 367 + 8614651 = 8615018

Showing the first eight; more decompositions exist.
