Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536492, here are decompositions:

11 + 31536481 = 31536492
89 + 31536403 = 31536492
101 + 31536391 = 31536492
109 + 31536383 = 31536492
131 + 31536361 = 31536492
139 + 31536353 = 31536492
179 + 31536313 = 31536492
199 + 31536293 = 31536492

Showing the first eight; more decompositions exist.
