Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592130, here are decompositions:

7 + 31592123 = 31592130
79 + 31592051 = 31592130
83 + 31592047 = 31592130
131 + 31591999 = 31592130
137 + 31591993 = 31592130
151 + 31591979 = 31592130
173 + 31591957 = 31592130
257 + 31591873 = 31592130

Showing the first eight; more decompositions exist.
