Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147524538, here are decompositions:

  • 7 + 2147524531 = 2147524538
  • 67 + 2147524471 = 2147524538
  • 97 + 2147524441 = 2147524538
  • 241 + 2147524297 = 2147524538
  • 307 + 2147524231 = 2147524538
  • 409 + 2147524129 = 2147524538
  • 457 + 2147524081 = 2147524538
  • 487 + 2147524051 = 2147524538

Showing the first eight; more decompositions exist.
