Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66432, here are decompositions:

  • 19 + 66413 = 66432
  • 29 + 66403 = 66432
  • 59 + 66373 = 66432
  • 71 + 66361 = 66432
  • 73 + 66359 = 66432
  • 89 + 66343 = 66432
  • 131 + 66301 = 66432
  • 139 + 66293 = 66432

Showing the first eight; more decompositions exist.
