Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497542, here are decompositions:

  • 19 + 2147497523 = 2147497542
  • 53 + 2147497489 = 2147497542
  • 61 + 2147497481 = 2147497542
  • 83 + 2147497459 = 2147497542
  • 131 + 2147497411 = 2147497542
  • 139 + 2147497403 = 2147497542
  • 149 + 2147497393 = 2147497542
  • 181 + 2147497361 = 2147497542

Showing the first eight; more decompositions exist.
