Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534132, here are decompositions:

11 + 31534121 = 31534132
29 + 31534103 = 31534132
53 + 31534079 = 31534132
59 + 31534073 = 31534132
173 + 31533959 = 31534132
293 + 31533839 = 31534132
359 + 31533773 = 31534132
491 + 31533641 = 31534132

Showing the first eight; more decompositions exist.
