Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729622, here are decompositions:

19 + 8729603 = 8729622
29 + 8729593 = 8729622
59 + 8729563 = 8729622
79 + 8729543 = 8729622
131 + 8729491 = 8729622
193 + 8729429 = 8729622
211 + 8729411 = 8729622
233 + 8729389 = 8729622

Showing the first eight; more decompositions exist.
