Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574154, here are decompositions:

23 + 31574131 = 31574154
47 + 31574107 = 31574154
61 + 31574093 = 31574154
83 + 31574071 = 31574154
107 + 31574047 = 31574154
113 + 31574041 = 31574154
193 + 31573961 = 31574154
197 + 31573957 = 31574154

Showing the first eight; more decompositions exist.
