Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535604, here are decompositions:

11 + 31535593 = 31535604
13 + 31535591 = 31535604
53 + 31535551 = 31535604
101 + 31535503 = 31535604
137 + 31535467 = 31535604
181 + 31535423 = 31535604
193 + 31535411 = 31535604
223 + 31535381 = 31535604

Showing the first eight; more decompositions exist.
