Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71532, here are decompositions:

  • 5 + 71527 = 71532
  • 29 + 71503 = 71532
  • 53 + 71479 = 71532
  • 59 + 71473 = 71532
  • 61 + 71471 = 71532
  • 79 + 71453 = 71532
  • 89 + 71443 = 71532
  • 103 + 71429 = 71532

Showing the first eight; more decompositions exist.
