Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622586, here are decompositions:

7 + 31622579 = 31622586
67 + 31622519 = 31622586
113 + 31622473 = 31622586
157 + 31622429 = 31622586
197 + 31622389 = 31622586
239 + 31622347 = 31622586
293 + 31622293 = 31622586
313 + 31622273 = 31622586

Showing the first eight; more decompositions exist.
