Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527534, here are decompositions:

11 + 31527523 = 31527534
13 + 31527521 = 31527534
37 + 31527497 = 31527534
43 + 31527491 = 31527534
53 + 31527481 = 31527534
127 + 31527407 = 31527534
191 + 31527343 = 31527534
211 + 31527323 = 31527534

Showing the first eight; more decompositions exist.
