Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547892, here are decompositions:

31 + 31547861 = 31547892
41 + 31547851 = 31547892
43 + 31547849 = 31547892
53 + 31547839 = 31547892
59 + 31547833 = 31547892
109 + 31547783 = 31547892
191 + 31547701 = 31547892
199 + 31547693 = 31547892

Showing the first eight; more decompositions exist.
