Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530274, here are decompositions:

5 + 31530269 = 31530274
71 + 31530203 = 31530274
101 + 31530173 = 31530274
131 + 31530143 = 31530274
257 + 31530017 = 31530274
383 + 31529891 = 31530274
431 + 31529843 = 31530274
491 + 31529783 = 31530274

Showing the first eight; more decompositions exist.
