Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514522, here are decompositions:

43 + 31514479 = 31514522
73 + 31514449 = 31514522
103 + 31514419 = 31514522
283 + 31514239 = 31514522
331 + 31514191 = 31514522
373 + 31514149 = 31514522
379 + 31514143 = 31514522
409 + 31514113 = 31514522

Showing the first eight; more decompositions exist.
