Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547702, here are decompositions:

19 + 31547683 = 31547702
31 + 31547671 = 31547702
61 + 31547641 = 31547702
73 + 31547629 = 31547702
163 + 31547539 = 31547702
223 + 31547479 = 31547702
421 + 31547281 = 31547702
499 + 31547203 = 31547702

Showing the first eight; more decompositions exist.
