Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536554, here are decompositions:

3 + 31536551 = 31536554
73 + 31536481 = 31536554
151 + 31536403 = 31536554
157 + 31536397 = 31536554
163 + 31536391 = 31536554
193 + 31536361 = 31536554
241 + 31536313 = 31536554
331 + 31536223 = 31536554

Showing the first eight; more decompositions exist.
