Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997892, here are decompositions:

  • 3 + 997889 = 997892
  • 13 + 997879 = 997892
  • 79 + 997813 = 997892
  • 109 + 997783 = 997892
  • 151 + 997741 = 997892
  • 193 + 997699 = 997892
  • 199 + 997693 = 997892
  • 211 + 997681 = 997892

Showing the first eight; more decompositions exist.
