Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530034, here are decompositions:

5 + 31530029 = 31530034
17 + 31530017 = 31530034
101 + 31529933 = 31530034
191 + 31529843 = 31530034
251 + 31529783 = 31530034
317 + 31529717 = 31530034
353 + 31529681 = 31530034
383 + 31529651 = 31530034

Showing the first eight; more decompositions exist.
