Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147570138, here are decompositions:

  • 79 + 2147570059 = 2147570138
  • 349 + 2147569789 = 2147570138
  • 367 + 2147569771 = 2147570138
  • 457 + 2147569681 = 2147570138
  • 577 + 2147569561 = 2147570138
  • 601 + 2147569537 = 2147570138
  • 607 + 2147569531 = 2147570138
  • 619 + 2147569519 = 2147570138

Showing the first eight; more decompositions exist.
