Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505572, here are decompositions:

  • 13 + 505559 = 505572
  • 59 + 505513 = 505572
  • 61 + 505511 = 505572
  • 71 + 505501 = 505572
  • 79 + 505493 = 505572
  • 103 + 505469 = 505572
  • 113 + 505459 = 505572
  • 163 + 505409 = 505572

Showing the first eight; more decompositions exist.
