Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45900, here are decompositions:

  • 7 + 45893 = 45900
  • 13 + 45887 = 45900
  • 31 + 45869 = 45900
  • 37 + 45863 = 45900
  • 47 + 45853 = 45900
  • 59 + 45841 = 45900
  • 67 + 45833 = 45900
  • 73 + 45827 = 45900

Showing the first eight; more decompositions exist.
