Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3578, here are decompositions:

  • 7 + 3571 = 3578
  • 19 + 3559 = 3578
  • 31 + 3547 = 3578
  • 37 + 3541 = 3578
  • 61 + 3517 = 3578
  • 67 + 3511 = 3578
  • 79 + 3499 = 3578
  • 109 + 3469 = 3578

Showing the first eight; more decompositions exist.
