Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147569954, here are decompositions:

  • 41 + 2147569913 = 2147569954
  • 107 + 2147569847 = 2147569954
  • 113 + 2147569841 = 2147569954
  • 251 + 2147569703 = 2147569954
  • 293 + 2147569661 = 2147569954
  • 347 + 2147569607 = 2147569954
  • 461 + 2147569493 = 2147569954
  • 557 + 2147569397 = 2147569954

Showing the first eight; more decompositions exist.
