Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532668, here are decompositions:

29 + 31532639 = 31532668
71 + 31532597 = 31532668
179 + 31532489 = 31532668
191 + 31532477 = 31532668
239 + 31532429 = 31532668
389 + 31532279 = 31532668
449 + 31532219 = 31532668
647 + 31532021 = 31532668

Showing the first eight; more decompositions exist.
