Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488438, here are decompositions:

  • 131 + 2147488307 = 2147488438
  • 191 + 2147488247 = 2147488438
  • 569 + 2147487869 = 2147488438
  • 659 + 2147487779 = 2147488438
  • 827 + 2147487611 = 2147488438
  • 839 + 2147487599 = 2147488438
  • 929 + 2147487509 = 2147488438
  • 1361 + 2147487077 = 2147488438

Showing the first eight; more decompositions exist.
