Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15622, here are decompositions:

3 + 15619 = 15622
41 + 15581 = 15622
53 + 15569 = 15622
71 + 15551 = 15622
149 + 15473 = 15622
179 + 15443 = 15622
239 + 15383 = 15622
263 + 15359 = 15622

Showing the first eight; more decompositions exist.
