Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567150, here are decompositions:

59 + 31567091 = 31567150
101 + 31567049 = 31567150
107 + 31567043 = 31567150
239 + 31566911 = 31567150
311 + 31566839 = 31567150
347 + 31566803 = 31567150
353 + 31566797 = 31567150
401 + 31566749 = 31567150

Showing the first eight; more decompositions exist.
