Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147377900, here are decompositions:

  • 29 + 2147377871 = 2147377900
  • 113 + 2147377787 = 2147377900
  • 233 + 2147377667 = 2147377900
  • 293 + 2147377607 = 2147377900
  • 359 + 2147377541 = 2147377900
  • 419 + 2147377481 = 2147377900
  • 431 + 2147377469 = 2147377900
  • 557 + 2147377343 = 2147377900

Showing the first eight; more decompositions exist.
