Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700784, here are decompositions:

  • 11 + 8700773 = 8700784
  • 17 + 8700767 = 8700784
  • 263 + 8700521 = 8700784
  • 311 + 8700473 = 8700784
  • 317 + 8700467 = 8700784
  • 353 + 8700431 = 8700784
  • 383 + 8700401 = 8700784
  • 401 + 8700383 = 8700784

Showing the first eight; more decompositions exist.
