Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532846, here are decompositions:

13 + 31532833 = 31532846
97 + 31532749 = 31532846
109 + 31532737 = 31532846
193 + 31532653 = 31532846
307 + 31532539 = 31532846
349 + 31532497 = 31532846
409 + 31532437 = 31532846
523 + 31532323 = 31532846

Showing the first eight; more decompositions exist.
