Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536380, here are decompositions:

19 + 31536361 = 31536380
67 + 31536313 = 31536380
157 + 31536223 = 31536380
193 + 31536187 = 31536380
283 + 31536097 = 31536380
331 + 31536049 = 31536380
397 + 31535983 = 31536380
433 + 31535947 = 31536380

Showing the first eight; more decompositions exist.
