Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31242, here are decompositions:

  • 5 + 31237 = 31242
  • 11 + 31231 = 31242
  • 19 + 31223 = 31242
  • 23 + 31219 = 31242
  • 53 + 31189 = 31242
  • 59 + 31183 = 31242
  • 61 + 31181 = 31242
  • 83 + 31159 = 31242

Showing the first eight; more decompositions exist.
