Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725878, here are decompositions:

  • 37 + 8725841 = 8725878
  • 47 + 8725831 = 8725878
  • 61 + 8725817 = 8725878
  • 79 + 8725799 = 8725878
  • 179 + 8725699 = 8725878
  • 197 + 8725681 = 8725878
  • 251 + 8725627 = 8725878
  • 257 + 8725621 = 8725878

Showing the first eight; more decompositions exist.
