Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631284, here are decompositions:

  • 7 + 8631277 = 8631284
  • 37 + 8631247 = 8631284
  • 283 + 8631001 = 8631284
  • 313 + 8630971 = 8631284
  • 433 + 8630851 = 8631284
  • 463 + 8630821 = 8631284
  • 547 + 8630737 = 8631284
  • 601 + 8630683 = 8631284

Showing the first eight; more decompositions exist.
