Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624990, here are decompositions:

  • 37 + 8624953 = 8624990
  • 61 + 8624929 = 8624990
  • 103 + 8624887 = 8624990
  • 109 + 8624881 = 8624990
  • 277 + 8624713 = 8624990
  • 313 + 8624677 = 8624990
  • 373 + 8624617 = 8624990
  • 487 + 8624503 = 8624990

Showing the first eight; more decompositions exist.
