Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626004, here are decompositions:

17 + 31625987 = 31626004
23 + 31625981 = 31626004
41 + 31625963 = 31626004
197 + 31625807 = 31626004
227 + 31625777 = 31626004
251 + 31625753 = 31626004
281 + 31625723 = 31626004
353 + 31625651 = 31626004

Showing the first eight; more decompositions exist.
