Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574070, here are decompositions:

23 + 31574047 = 31574070
29 + 31574041 = 31574070
71 + 31573999 = 31574070
103 + 31573967 = 31574070
109 + 31573961 = 31574070
113 + 31573957 = 31574070
139 + 31573931 = 31574070
211 + 31573859 = 31574070

Showing the first eight; more decompositions exist.
