Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529334, here are decompositions:

13 + 31529321 = 31529334
61 + 31529273 = 31529334
167 + 31529167 = 31529334
227 + 31529107 = 31529334
281 + 31529053 = 31529334
337 + 31528997 = 31529334
367 + 31528967 = 31529334
491 + 31528843 = 31529334

Showing the first eight; more decompositions exist.
