Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536474, here are decompositions:

71 + 31536403 = 31536474
83 + 31536391 = 31536474
113 + 31536361 = 31536474
127 + 31536347 = 31536474
181 + 31536293 = 31536474
251 + 31536223 = 31536474
271 + 31536203 = 31536474
313 + 31536161 = 31536474

Showing the first eight; more decompositions exist.
