Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66320, here are decompositions:

  • 19 + 66301 = 66320
  • 151 + 66169 = 66320
  • 211 + 66109 = 66320
  • 283 + 66037 = 66320
  • 337 + 65983 = 66320
  • 421 + 65899 = 66320
  • 439 + 65881 = 66320
  • 601 + 65719 = 66320

Showing the first eight; more decompositions exist.
