Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550492, here are decompositions:

13 + 31550479 = 31550492
31 + 31550461 = 31550492
139 + 31550353 = 31550492
163 + 31550329 = 31550492
241 + 31550251 = 31550492
271 + 31550221 = 31550492
313 + 31550179 = 31550492
373 + 31550119 = 31550492

Showing the first eight; more decompositions exist.
