Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622300, here are decompositions:

7 + 31622293 = 31622300
13 + 31622287 = 31622300
19 + 31622281 = 31622300
43 + 31622257 = 31622300
181 + 31622119 = 31622300
337 + 31621963 = 31622300
421 + 31621879 = 31622300
547 + 31621753 = 31622300

Showing the first eight; more decompositions exist.
