Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640232, here are decompositions:

  • 11 + 8640221 = 8640232
  • 71 + 8640161 = 8640232
  • 173 + 8640059 = 8640232
  • 281 + 8639951 = 8640232
  • 311 + 8639921 = 8640232
  • 383 + 8639849 = 8640232
  • 479 + 8639753 = 8640232
  • 521 + 8639711 = 8640232

Showing the first eight; more decompositions exist.
