Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8653428, here are decompositions:

  • 67 + 8653361 = 8653428
  • 101 + 8653327 = 8653428
  • 109 + 8653319 = 8653428
  • 131 + 8653297 = 8653428
  • 149 + 8653279 = 8653428
  • 167 + 8653261 = 8653428
  • 191 + 8653237 = 8653428
  • 197 + 8653231 = 8653428

Showing the first eight; more decompositions exist.
