Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711378, here are decompositions:

  • 19 + 8711359 = 8711378
  • 31 + 8711347 = 8711378
  • 199 + 8711179 = 8711378
  • 241 + 8711137 = 8711378
  • 307 + 8711071 = 8711378
  • 367 + 8711011 = 8711378
  • 421 + 8710957 = 8711378
  • 439 + 8710939 = 8711378

Showing the first eight; more decompositions exist.
