Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671904, here are decompositions:

  • 67 + 8671837 = 8671904
  • 193 + 8671711 = 8671904
  • 271 + 8671633 = 8671904
  • 331 + 8671573 = 8671904
  • 433 + 8671471 = 8671904
  • 457 + 8671447 = 8671904
  • 463 + 8671441 = 8671904
  • 523 + 8671381 = 8671904

Showing the first eight; more decompositions exist.
