Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31487014, here are decompositions:

47 + 31486967 = 31487014
263 + 31486751 = 31487014
281 + 31486733 = 31487014
353 + 31486661 = 31487014
401 + 31486613 = 31487014
443 + 31486571 = 31487014
521 + 31486493 = 31487014
557 + 31486457 = 31487014

Showing the first eight; more decompositions exist.
