Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536356, here are decompositions:

3 + 31536353 = 31536356
43 + 31536313 = 31536356
307 + 31536049 = 31536356
337 + 31536019 = 31536356
373 + 31535983 = 31536356
409 + 31535947 = 31536356
547 + 31535809 = 31536356
853 + 31535503 = 31536356

Showing the first eight; more decompositions exist.
