Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80566, here are decompositions:

  • 29 + 80537 = 80566
  • 53 + 80513 = 80566
  • 137 + 80429 = 80566
  • 179 + 80387 = 80566
  • 197 + 80369 = 80566
  • 257 + 80309 = 80566
  • 293 + 80273 = 80566
  • 359 + 80207 = 80566

Showing the first eight; more decompositions exist.
