Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592774, here are decompositions:

13 + 31592761 = 31592774
97 + 31592677 = 31592774
223 + 31592551 = 31592774
307 + 31592467 = 31592774
337 + 31592437 = 31592774
397 + 31592377 = 31592774
463 + 31592311 = 31592774
571 + 31592203 = 31592774

Showing the first eight; more decompositions exist.
