Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75900, here are decompositions:

  • 17 + 75883 = 75900
  • 31 + 75869 = 75900
  • 47 + 75853 = 75900
  • 67 + 75833 = 75900
  • 79 + 75821 = 75900
  • 103 + 75797 = 75900
  • 107 + 75793 = 75900
  • 113 + 75787 = 75900

Showing the first eight; more decompositions exist.
