Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530214, here are decompositions:

3 + 31530211 = 31530214
11 + 31530203 = 31530214
17 + 31530197 = 31530214
41 + 31530173 = 31530214
71 + 31530143 = 31530214
197 + 31530017 = 31530214
281 + 31529933 = 31530214
431 + 31529783 = 31530214

Showing the first eight; more decompositions exist.
