Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172584, here are decompositions:

  • 11 + 172573 = 172584
  • 23 + 172561 = 172584
  • 31 + 172553 = 172584
  • 43 + 172541 = 172584
  • 67 + 172517 = 172584
  • 151 + 172433 = 172584
  • 157 + 172427 = 172584
  • 163 + 172421 = 172584

Showing the first eight; more decompositions exist.
