Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28236, here are decompositions:

  • 7 + 28229 = 28236
  • 17 + 28219 = 28236
  • 53 + 28183 = 28236
  • 73 + 28163 = 28236
  • 113 + 28123 = 28236
  • 127 + 28109 = 28236
  • 137 + 28099 = 28236
  • 139 + 28097 = 28236

Showing the first eight; more decompositions exist.
