Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147574146, here are decompositions:

  • 19 + 2147574127 = 2147574146
  • 103 + 2147574043 = 2147574146
  • 307 + 2147573839 = 2147574146
  • 397 + 2147573749 = 2147574146
  • 457 + 2147573689 = 2147574146
  • 547 + 2147573599 = 2147574146
  • 607 + 2147573539 = 2147574146
  • 709 + 2147573437 = 2147574146

Showing the first eight; more decompositions exist.
