Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547756, here are decompositions:

7 + 31547749 = 31547756
73 + 31547683 = 31547756
127 + 31547629 = 31547756
139 + 31547617 = 31547756
199 + 31547557 = 31547756
277 + 31547479 = 31547756
307 + 31547449 = 31547756
439 + 31547317 = 31547756

Showing the first eight; more decompositions exist.
