Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622900, here are decompositions:

7 + 31622893 = 31622900
19 + 31622881 = 31622900
37 + 31622863 = 31622900
97 + 31622803 = 31622900
157 + 31622743 = 31622900
229 + 31622671 = 31622900
271 + 31622629 = 31622900
409 + 31622491 = 31622900

Showing the first eight; more decompositions exist.
