Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489438, here are decompositions:

  • 37 + 2147489401 = 2147489438
  • 139 + 2147489299 = 2147489438
  • 349 + 2147489089 = 2147489438
  • 379 + 2147489059 = 2147489438
  • 421 + 2147489017 = 2147489438
  • 571 + 2147488867 = 2147489438
  • 859 + 2147488579 = 2147489438
  • 1009 + 2147488429 = 2147489438

Showing the first eight; more decompositions exist.
