Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622452, here are decompositions:

23 + 31622429 = 31622452
83 + 31622369 = 31622452
179 + 31622273 = 31622452
263 + 31622189 = 31622452
269 + 31622183 = 31622452
311 + 31622141 = 31622452
503 + 31621949 = 31622452
773 + 31621679 = 31622452

Showing the first eight; more decompositions exist.
