Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615122, here are decompositions:

  • 23 + 8615099 = 8615122
  • 59 + 8615063 = 8615122
  • 71 + 8615051 = 8615122
  • 149 + 8614973 = 8615122
  • 233 + 8614889 = 8615122
  • 239 + 8614883 = 8615122
  • 281 + 8614841 = 8615122
  • 293 + 8614829 = 8615122

Showing the first eight; more decompositions exist.
