Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514474, here are decompositions:

73 + 31514401 = 31514474
283 + 31514191 = 31514474
331 + 31514143 = 31514474
373 + 31514101 = 31514474
487 + 31513987 = 31514474
547 + 31513927 = 31514474
601 + 31513873 = 31514474
631 + 31513843 = 31514474

Showing the first eight; more decompositions exist.
