Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567264, here are decompositions:

23 + 31567241 = 31567264
107 + 31567157 = 31567264
173 + 31567091 = 31567264
353 + 31566911 = 31567264
401 + 31566863 = 31567264
461 + 31566803 = 31567264
467 + 31566797 = 31567264
653 + 31566611 = 31567264

Showing the first eight; more decompositions exist.
