Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514444, here are decompositions:

43 + 31514401 = 31514444
223 + 31514221 = 31514444
331 + 31514113 = 31514444
421 + 31514023 = 31514444
457 + 31513987 = 31514444
487 + 31513957 = 31514444
571 + 31513873 = 31514444
601 + 31513843 = 31514444

Showing the first eight; more decompositions exist.
