Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624900, here are decompositions:

  • 13 + 8624887 = 8624900
  • 19 + 8624881 = 8624900
  • 79 + 8624821 = 8624900
  • 127 + 8624773 = 8624900
  • 223 + 8624677 = 8624900
  • 283 + 8624617 = 8624900
  • 397 + 8624503 = 8624900
  • 547 + 8624353 = 8624900

Showing the first eight; more decompositions exist.
