Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626008, here are decompositions:

97 + 31625911 = 31626008
229 + 31625779 = 31626008
241 + 31625767 = 31626008
277 + 31625731 = 31626008
409 + 31625599 = 31626008
499 + 31625509 = 31626008
541 + 31625467 = 31626008
577 + 31625431 = 31626008

Showing the first eight; more decompositions exist.
