Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 74870, here are decompositions:

  • 13 + 74857 = 74870
  • 43 + 74827 = 74870
  • 73 + 74797 = 74870
  • 109 + 74761 = 74870
  • 139 + 74731 = 74870
  • 151 + 74719 = 74870
  • 157 + 74713 = 74870
  • 163 + 74707 = 74870

Showing the first eight; more decompositions exist.
