Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547706, here are decompositions:

5 + 31547701 = 31547706
13 + 31547693 = 31547706
23 + 31547683 = 31547706
89 + 31547617 = 31547706
97 + 31547609 = 31547706
149 + 31547557 = 31547706
167 + 31547539 = 31547706
199 + 31547507 = 31547706

Showing the first eight; more decompositions exist.
