Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592294, here are decompositions:

3 + 31592291 = 31592294
37 + 31592257 = 31592294
241 + 31592053 = 31592294
337 + 31591957 = 31592294
421 + 31591873 = 31592294
457 + 31591837 = 31592294
571 + 31591723 = 31592294
607 + 31591687 = 31592294

Showing the first eight; more decompositions exist.
