Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547932, here are decompositions:

11 + 31547921 = 31547932
71 + 31547861 = 31547932
83 + 31547849 = 31547932
149 + 31547783 = 31547932
239 + 31547693 = 31547932
401 + 31547531 = 31547932
443 + 31547489 = 31547932
461 + 31547471 = 31547932

Showing the first eight; more decompositions exist.
