Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147586550, here are decompositions:

  • 3 + 2147586547 = 2147586550
  • 41 + 2147586509 = 2147586550
  • 89 + 2147586461 = 2147586550
  • 251 + 2147586299 = 2147586550
  • 257 + 2147586293 = 2147586550
  • 293 + 2147586257 = 2147586550
  • 383 + 2147586167 = 2147586550
  • 479 + 2147586071 = 2147586550

Showing the first eight; more decompositions exist.
