Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720364, here are decompositions:

  • 17 + 8720347 = 8720364
  • 43 + 8720321 = 8720364
  • 47 + 8720317 = 8720364
  • 53 + 8720311 = 8720364
  • 83 + 8720281 = 8720364
  • 131 + 8720233 = 8720364
  • 137 + 8720227 = 8720364
  • 173 + 8720191 = 8720364

Showing the first eight; more decompositions exist.
