Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574130, here are decompositions:

23 + 31574107 = 31574130
31 + 31574099 = 31574130
37 + 31574093 = 31574130
59 + 31574071 = 31574130
83 + 31574047 = 31574130
89 + 31574041 = 31574130
109 + 31574021 = 31574130
131 + 31573999 = 31574130

Showing the first eight; more decompositions exist.
