Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147557522, here are decompositions:

  • 41 + 2147557481 = 2147557522
  • 59 + 2147557463 = 2147557522
  • 191 + 2147557331 = 2147557522
  • 401 + 2147557121 = 2147557522
  • 491 + 2147557031 = 2147557522
  • 503 + 2147557019 = 2147557522
  • 563 + 2147556959 = 2147557522
  • 569 + 2147556953 = 2147557522

Showing the first eight; more decompositions exist.
