Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729300, here are decompositions:

  • 61 + 8729239 = 8729300
  • 79 + 8729221 = 8729300
  • 109 + 8729191 = 8729300
  • 127 + 8729173 = 8729300
  • 193 + 8729107 = 8729300
  • 241 + 8729059 = 8729300
  • 313 + 8728987 = 8729300
  • 331 + 8728969 = 8729300

Showing the first eight; more decompositions exist.
