Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87450, here are decompositions:

  • 7 + 87443 = 87450
  • 17 + 87433 = 87450
  • 23 + 87427 = 87450
  • 29 + 87421 = 87450
  • 43 + 87407 = 87450
  • 47 + 87403 = 87450
  • 67 + 87383 = 87450
  • 113 + 87337 = 87450

Showing the first eight; more decompositions exist.
