Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536004, here are decompositions:

23 + 31535981 = 31536004
173 + 31535831 = 31536004
251 + 31535753 = 31536004
257 + 31535747 = 31536004
263 + 31535741 = 31536004
347 + 31535657 = 31536004
587 + 31535417 = 31536004
593 + 31535411 = 31536004

Showing the first eight; more decompositions exist.
