Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671488, here are decompositions:

  • 17 + 8671471 = 8671488
  • 19 + 8671469 = 8671488
  • 31 + 8671457 = 8671488
  • 41 + 8671447 = 8671488
  • 47 + 8671441 = 8671488
  • 61 + 8671427 = 8671488
  • 79 + 8671409 = 8671488
  • 107 + 8671381 = 8671488

Showing the first eight; more decompositions exist.
