Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547764, here are decompositions:

71 + 31547693 = 31547764
173 + 31547591 = 31547764
233 + 31547531 = 31547764
257 + 31547507 = 31547764
293 + 31547471 = 31547764
461 + 31547303 = 31547764
467 + 31547297 = 31547764
503 + 31547261 = 31547764

Showing the first eight; more decompositions exist.
