Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574150, here are decompositions:

19 + 31574131 = 31574150
43 + 31574107 = 31574150
79 + 31574071 = 31574150
103 + 31574047 = 31574150
109 + 31574041 = 31574150
151 + 31573999 = 31574150
193 + 31573957 = 31574150
331 + 31573819 = 31574150

Showing the first eight; more decompositions exist.
