Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592148, here are decompositions:

19 + 31592129 = 31592148
97 + 31592051 = 31592148
101 + 31592047 = 31592148
109 + 31592039 = 31592148
149 + 31591999 = 31592148
151 + 31591997 = 31592148
191 + 31591957 = 31592148
239 + 31591909 = 31592148

Showing the first eight; more decompositions exist.
