Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547628, here are decompositions:

11 + 31547617 = 31547628
19 + 31547609 = 31547628
37 + 31547591 = 31547628
71 + 31547557 = 31547628
89 + 31547539 = 31547628
97 + 31547531 = 31547628
109 + 31547519 = 31547628
139 + 31547489 = 31547628

Showing the first eight; more decompositions exist.
