Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592152, here are decompositions:

3 + 31592149 = 31592152
23 + 31592129 = 31592152
29 + 31592123 = 31592152
101 + 31592051 = 31592152
113 + 31592039 = 31592152
173 + 31591979 = 31592152
239 + 31591913 = 31592152
359 + 31591793 = 31592152

Showing the first eight; more decompositions exist.
