Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547644, here are decompositions:

3 + 31547641 = 31547644
53 + 31547591 = 31547644
113 + 31547531 = 31547644
137 + 31547507 = 31547644
173 + 31547471 = 31547644
347 + 31547297 = 31547644
383 + 31547261 = 31547644
467 + 31547177 = 31547644

Showing the first eight; more decompositions exist.
