Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532674, here are decompositions:

101 + 31532573 = 31532674
167 + 31532507 = 31532674
197 + 31532477 = 31532674
557 + 31532117 = 31532674
653 + 31532021 = 31532674
743 + 31531931 = 31532674
857 + 31531817 = 31532674
947 + 31531727 = 31532674

Showing the first eight; more decompositions exist.
