Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592564, here are decompositions:

7 + 31592557 = 31592564
13 + 31592551 = 31592564
97 + 31592467 = 31592564
127 + 31592437 = 31592564
307 + 31592257 = 31592564
571 + 31591993 = 31592564
607 + 31591957 = 31592564
691 + 31591873 = 31592564

Showing the first eight; more decompositions exist.
