Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547652, here are decompositions:

11 + 31547641 = 31547652
23 + 31547629 = 31547652
43 + 31547609 = 31547652
61 + 31547591 = 31547652
113 + 31547539 = 31547652
163 + 31547489 = 31547652
173 + 31547479 = 31547652
181 + 31547471 = 31547652

Showing the first eight; more decompositions exist.
