Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550692, here are decompositions:

11 + 31550681 = 31550692
149 + 31550543 = 31550692
233 + 31550459 = 31550692
353 + 31550339 = 31550692
479 + 31550213 = 31550692
491 + 31550201 = 31550692
599 + 31550093 = 31550692
773 + 31549919 = 31550692

Showing the first eight; more decompositions exist.
