Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560366, here are decompositions:

23 + 31560343 = 31560366
59 + 31560307 = 31560366
67 + 31560299 = 31560366
73 + 31560293 = 31560366
127 + 31560239 = 31560366
139 + 31560227 = 31560366
193 + 31560173 = 31560366
269 + 31560097 = 31560366

Showing the first eight; more decompositions exist.
