Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592514, here are decompositions:

47 + 31592467 = 31592514
61 + 31592453 = 31592514
67 + 31592447 = 31592514
97 + 31592417 = 31592514
103 + 31592411 = 31592514
137 + 31592377 = 31592514
157 + 31592357 = 31592514
167 + 31592347 = 31592514

Showing the first eight; more decompositions exist.
