Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592156, here are decompositions:

7 + 31592149 = 31592156
103 + 31592053 = 31592156
109 + 31592047 = 31592156
157 + 31591999 = 31592156
163 + 31591993 = 31592156
199 + 31591957 = 31592156
283 + 31591873 = 31592156
313 + 31591843 = 31592156

Showing the first eight; more decompositions exist.
