Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567174, here are decompositions:

17 + 31567157 = 31567174
83 + 31567091 = 31567174
131 + 31567043 = 31567174
263 + 31566911 = 31567174
311 + 31566863 = 31567174
347 + 31566827 = 31567174
461 + 31566713 = 31567174
563 + 31566611 = 31567174

Showing the first eight; more decompositions exist.
