Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547546, here are decompositions:

7 + 31547539 = 31547546
67 + 31547479 = 31547546
97 + 31547449 = 31547546
229 + 31547317 = 31547546
337 + 31547209 = 31547546
577 + 31546969 = 31547546
733 + 31546813 = 31547546
739 + 31546807 = 31547546

Showing the first eight; more decompositions exist.
