Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550522, here are decompositions:

13 + 31550509 = 31550522
43 + 31550479 = 31550522
61 + 31550461 = 31550522
151 + 31550371 = 31550522
193 + 31550329 = 31550522
271 + 31550251 = 31550522
373 + 31550149 = 31550522
541 + 31549981 = 31550522

Showing the first eight; more decompositions exist.
