Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530014, here are decompositions:

13 + 31530001 = 31530014
37 + 31529977 = 31530014
337 + 31529677 = 31530014
421 + 31529593 = 31530014
457 + 31529557 = 31530014
463 + 31529551 = 31530014
601 + 31529413 = 31530014
661 + 31529353 = 31530014

Showing the first eight; more decompositions exist.
