Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33517578, here are decompositions:

  • 5 + 33517573 = 33517578
  • 19 + 33517559 = 33517578
  • 41 + 33517537 = 33517578
  • 47 + 33517531 = 33517578
  • 79 + 33517499 = 33517578
  • 97 + 33517481 = 33517578
  • 109 + 33517469 = 33517578
  • 167 + 33517411 = 33517578

Showing the first eight; more decompositions exist.
