Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592142, here are decompositions:

13 + 31592129 = 31592142
19 + 31592123 = 31592142
89 + 31592053 = 31592142
103 + 31592039 = 31592142
149 + 31591993 = 31592142
163 + 31591979 = 31592142
229 + 31591913 = 31592142
233 + 31591909 = 31592142

Showing the first eight; more decompositions exist.
