Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496522, here are decompositions:

3 + 31496519 = 31496522
73 + 31496449 = 31496522
103 + 31496419 = 31496522
151 + 31496371 = 31496522
193 + 31496329 = 31496522
229 + 31496293 = 31496522
313 + 31496209 = 31496522
349 + 31496173 = 31496522

Showing the first eight; more decompositions exist.
