Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592474, here are decompositions:

7 + 31592467 = 31592474
37 + 31592437 = 31592474
97 + 31592377 = 31592474
127 + 31592347 = 31592474
163 + 31592311 = 31592474
271 + 31592203 = 31592474
313 + 31592161 = 31592474
421 + 31592053 = 31592474

Showing the first eight; more decompositions exist.
