Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17850, here are decompositions:

  • 11 + 17839 = 17850
  • 13 + 17837 = 17850
  • 23 + 17827 = 17850
  • 43 + 17807 = 17850
  • 59 + 17791 = 17850
  • 61 + 17789 = 17850
  • 67 + 17783 = 17850
  • 89 + 17761 = 17850

Showing the first eight; more decompositions exist.
