Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592276, here are decompositions:

19 + 31592257 = 31592276
73 + 31592203 = 31592276
103 + 31592173 = 31592276
127 + 31592149 = 31592276
223 + 31592053 = 31592276
229 + 31592047 = 31592276
277 + 31591999 = 31592276
283 + 31591993 = 31592276

Showing the first eight; more decompositions exist.
