Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592154, here are decompositions:

5 + 31592149 = 31592154
31 + 31592123 = 31592154
101 + 31592053 = 31592154
103 + 31592051 = 31592154
107 + 31592047 = 31592154
157 + 31591997 = 31592154
197 + 31591957 = 31592154
241 + 31591913 = 31592154

Showing the first eight; more decompositions exist.
