Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536534, here are decompositions:

5 + 31536529 = 31536534
13 + 31536521 = 31536534
53 + 31536481 = 31536534
131 + 31536403 = 31536534
137 + 31536397 = 31536534
151 + 31536383 = 31536534
173 + 31536361 = 31536534
181 + 31536353 = 31536534

Showing the first eight; more decompositions exist.
