Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592264, here are decompositions:

7 + 31592257 = 31592264
61 + 31592203 = 31592264
103 + 31592161 = 31592264
211 + 31592053 = 31592264
271 + 31591993 = 31592264
307 + 31591957 = 31592264
397 + 31591867 = 31592264
421 + 31591843 = 31592264

Showing the first eight; more decompositions exist.
