Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592654, here are decompositions:

3 + 31592651 = 31592654
13 + 31592641 = 31592654
97 + 31592557 = 31592654
103 + 31592551 = 31592654
277 + 31592377 = 31592654
307 + 31592347 = 31592654
397 + 31592257 = 31592654
601 + 31592053 = 31592654

Showing the first eight; more decompositions exist.
