Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536678, here are decompositions:

71 + 31536607 = 31536678
127 + 31536551 = 31536678
139 + 31536539 = 31536678
149 + 31536529 = 31536678
157 + 31536521 = 31536678
179 + 31536499 = 31536678
197 + 31536481 = 31536678
281 + 31536397 = 31536678

Showing the first eight; more decompositions exist.
