Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691622, here are decompositions:

29 + 8691593 = 8691622
41 + 8691581 = 8691622
113 + 8691509 = 8691622
239 + 8691383 = 8691622
263 + 8691359 = 8691622
353 + 8691269 = 8691622
383 + 8691239 = 8691622
503 + 8691119 = 8691622

Showing the first eight; more decompositions exist.
