Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536548, here are decompositions:

19 + 31536529 = 31536548
67 + 31536481 = 31536548
151 + 31536397 = 31536548
157 + 31536391 = 31536548
487 + 31536061 = 31536548
499 + 31536049 = 31536548
601 + 31535947 = 31536548
607 + 31535941 = 31536548

Showing the first eight; more decompositions exist.
