Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592374, here are decompositions:

5 + 31592369 = 31592374
17 + 31592357 = 31592374
83 + 31592291 = 31592374
251 + 31592123 = 31592374
461 + 31591913 = 31592374
641 + 31591733 = 31592374
773 + 31591601 = 31592374
797 + 31591577 = 31592374

Showing the first eight; more decompositions exist.
