Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592178, here are decompositions:

5 + 31592173 = 31592178
17 + 31592161 = 31592178
19 + 31592159 = 31592178
29 + 31592149 = 31592178
127 + 31592051 = 31592178
131 + 31592047 = 31592178
139 + 31592039 = 31592178
179 + 31591999 = 31592178

Showing the first eight; more decompositions exist.
