Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530364, here are decompositions:

17 + 31530347 = 31530364
23 + 31530341 = 31530364
53 + 31530311 = 31530364
71 + 31530293 = 31530364
167 + 31530197 = 31530364
191 + 31530173 = 31530364
347 + 31530017 = 31530364
431 + 31529933 = 31530364

Showing the first eight; more decompositions exist.
