Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72534, here are decompositions:

  • 31 + 72503 = 72534
  • 37 + 72497 = 72534
  • 41 + 72493 = 72534
  • 53 + 72481 = 72534
  • 67 + 72467 = 72534
  • 73 + 72461 = 72534
  • 103 + 72431 = 72534
  • 113 + 72421 = 72534

Showing the first eight; more decompositions exist.
