Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477412, here are decompositions:

13 + 31477399 = 31477412
61 + 31477351 = 31477412
199 + 31477213 = 31477412
271 + 31477141 = 31477412
313 + 31477099 = 31477412
349 + 31477063 = 31477412
541 + 31476871 = 31477412
613 + 31476799 = 31477412

Showing the first eight; more decompositions exist.
