Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567348, here are decompositions:

107 + 31567241 = 31567348
191 + 31567157 = 31567348
257 + 31567091 = 31567348
509 + 31566839 = 31567348
521 + 31566827 = 31567348
599 + 31566749 = 31567348
821 + 31566527 = 31567348
971 + 31566377 = 31567348

Showing the first eight; more decompositions exist.
