Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622624, here are decompositions:

151 + 31622473 = 31622624
157 + 31622467 = 31622624
277 + 31622347 = 31622624
331 + 31622293 = 31622624
337 + 31622287 = 31622624
367 + 31622257 = 31622624
457 + 31622167 = 31622624
577 + 31622047 = 31622624

Showing the first eight; more decompositions exist.
