Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547748, here are decompositions:

17 + 31547731 = 31547748
41 + 31547707 = 31547748
47 + 31547701 = 31547748
107 + 31547641 = 31547748
131 + 31547617 = 31547748
139 + 31547609 = 31547748
157 + 31547591 = 31547748
191 + 31547557 = 31547748

Showing the first eight; more decompositions exist.
