Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72318, here are decompositions:

  • 5 + 72313 = 72318
  • 11 + 72307 = 72318
  • 31 + 72287 = 72318
  • 41 + 72277 = 72318
  • 47 + 72271 = 72318
  • 67 + 72251 = 72318
  • 89 + 72229 = 72318
  • 97 + 72221 = 72318

Showing the first eight; more decompositions exist.
