Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592184, here are decompositions:

11 + 31592173 = 31592184
23 + 31592161 = 31592184
61 + 31592123 = 31592184
131 + 31592053 = 31592184
137 + 31592047 = 31592184
191 + 31591993 = 31592184
227 + 31591957 = 31592184
271 + 31591913 = 31592184

Showing the first eight; more decompositions exist.
