Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532764, here are decompositions:

71 + 31532693 = 31532764
167 + 31532597 = 31532764
191 + 31532573 = 31532764
257 + 31532507 = 31532764
503 + 31532261 = 31532764
647 + 31532117 = 31532764
701 + 31532063 = 31532764
743 + 31532021 = 31532764

Showing the first eight; more decompositions exist.
