Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536522, here are decompositions:

23 + 31536499 = 31536522
41 + 31536481 = 31536522
131 + 31536391 = 31536522
139 + 31536383 = 31536522
163 + 31536359 = 31536522
229 + 31536293 = 31536522
421 + 31536101 = 31536522
461 + 31536061 = 31536522

Showing the first eight; more decompositions exist.
