Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547568, here are decompositions:

11 + 31547557 = 31547568
29 + 31547539 = 31547568
37 + 31547531 = 31547568
61 + 31547507 = 31547568
79 + 31547489 = 31547568
89 + 31547479 = 31547568
97 + 31547471 = 31547568
109 + 31547459 = 31547568

Showing the first eight; more decompositions exist.
