Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547734, here are decompositions:

3 + 31547731 = 31547734
41 + 31547693 = 31547734
227 + 31547507 = 31547734
263 + 31547471 = 31547734
293 + 31547441 = 31547734
431 + 31547303 = 31547734
467 + 31547267 = 31547734
503 + 31547231 = 31547734

Showing the first eight; more decompositions exist.
