Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536704, here are decompositions:

7 + 31536697 = 31536704
97 + 31536607 = 31536704
223 + 31536481 = 31536704
307 + 31536397 = 31536704
313 + 31536391 = 31536704
607 + 31536097 = 31536704
643 + 31536061 = 31536704
757 + 31535947 = 31536704

Showing the first eight; more decompositions exist.
