Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547704, here are decompositions:

3 + 31547701 = 31547704
11 + 31547693 = 31547704
113 + 31547591 = 31547704
173 + 31547531 = 31547704
197 + 31547507 = 31547704
233 + 31547471 = 31547704
263 + 31547441 = 31547704
347 + 31547357 = 31547704

Showing the first eight; more decompositions exist.
