Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631684, here are decompositions:

  • 11 + 8631673 = 8631684
  • 67 + 8631617 = 8631684
  • 73 + 8631611 = 8631684
  • 151 + 8631533 = 8631684
  • 167 + 8631517 = 8631684
  • 233 + 8631451 = 8631684
  • 283 + 8631401 = 8631684
  • 293 + 8631391 = 8631684

Showing the first eight; more decompositions exist.
