Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748432, here are decompositions:

  • 13 + 8748419 = 8748432
  • 19 + 8748413 = 8748432
  • 29 + 8748403 = 8748432
  • 71 + 8748361 = 8748432
  • 73 + 8748359 = 8748432
  • 101 + 8748331 = 8748432
  • 103 + 8748329 = 8748432
  • 109 + 8748323 = 8748432

Showing the first eight; more decompositions exist.
