Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643562, here are decompositions:

  • 23 + 8643539 = 8643562
  • 41 + 8643521 = 8643562
  • 281 + 8643281 = 8643562
  • 353 + 8643209 = 8643562
  • 419 + 8643143 = 8643562
  • 479 + 8643083 = 8643562
  • 503 + 8643059 = 8643562
  • 509 + 8643053 = 8643562

Showing the first eight; more decompositions exist.
