Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179542, here are decompositions:

  • 23 + 179519 = 179542
  • 59 + 179483 = 179542
  • 71 + 179471 = 179542
  • 89 + 179453 = 179542
  • 101 + 179441 = 179542
  • 113 + 179429 = 179542
  • 131 + 179411 = 179542
  • 149 + 179393 = 179542

Showing the first eight; more decompositions exist.
