Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87630, here are decompositions:

  • 7 + 87623 = 87630
  • 17 + 87613 = 87630
  • 41 + 87589 = 87630
  • 43 + 87587 = 87630
  • 47 + 87583 = 87630
  • 71 + 87559 = 87630
  • 73 + 87557 = 87630
  • 83 + 87547 = 87630

Showing the first eight; more decompositions exist.
