Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592190, here are decompositions:

17 + 31592173 = 31592190
29 + 31592161 = 31592190
31 + 31592159 = 31592190
41 + 31592149 = 31592190
61 + 31592129 = 31592190
67 + 31592123 = 31592190
137 + 31592053 = 31592190
139 + 31592051 = 31592190

Showing the first eight; more decompositions exist.
