Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8741638, here are decompositions:

29 + 8741609 = 8741638
167 + 8741471 = 8741638
179 + 8741459 = 8741638
317 + 8741321 = 8741638
359 + 8741279 = 8741638
491 + 8741147 = 8741638
509 + 8741129 = 8741638
797 + 8740841 = 8741638

Showing the first eight; more decompositions exist.
