Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567204, here are decompositions:

47 + 31567157 = 31567204
113 + 31567091 = 31567204
293 + 31566911 = 31567204
401 + 31566803 = 31567204
467 + 31566737 = 31567204
491 + 31566713 = 31567204
593 + 31566611 = 31567204
677 + 31566527 = 31567204

Showing the first eight; more decompositions exist.
