Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532962, here are decompositions:

3 + 31532959 = 31532962
23 + 31532939 = 31532962
89 + 31532873 = 31532962
269 + 31532693 = 31532962
389 + 31532573 = 31532962
683 + 31532279 = 31532962
701 + 31532261 = 31532962
743 + 31532219 = 31532962

Showing the first eight; more decompositions exist.
