Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8754640, here are decompositions:

17 + 8754623 = 8754640
53 + 8754587 = 8754640
101 + 8754539 = 8754640
179 + 8754461 = 8754640
239 + 8754401 = 8754640
359 + 8754281 = 8754640
383 + 8754257 = 8754640
509 + 8754131 = 8754640

Showing the first eight; more decompositions exist.
