Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529474, here are decompositions:

3 + 31529471 = 31529474
43 + 31529431 = 31529474
61 + 31529413 = 31529474
127 + 31529347 = 31529474
307 + 31529167 = 31529474
367 + 31529107 = 31529474
421 + 31529053 = 31529474
631 + 31528843 = 31529474

Showing the first eight; more decompositions exist.
