Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556522, here are decompositions:

43 + 31556479 = 31556522
61 + 31556461 = 31556522
181 + 31556341 = 31556522
199 + 31556323 = 31556522
229 + 31556293 = 31556522
373 + 31556149 = 31556522
379 + 31556143 = 31556522
409 + 31556113 = 31556522

Showing the first eight; more decompositions exist.
