Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18756, here are decompositions:

  • 7 + 18749 = 18756
  • 13 + 18743 = 18756
  • 37 + 18719 = 18756
  • 43 + 18713 = 18756
  • 139 + 18617 = 18756
  • 163 + 18593 = 18756
  • 173 + 18583 = 18756
  • 233 + 18523 = 18756

Showing the first eight; more decompositions exist.
