Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592366, here are decompositions:

19 + 31592347 = 31592366
109 + 31592257 = 31592366
163 + 31592203 = 31592366
193 + 31592173 = 31592366
313 + 31592053 = 31592366
367 + 31591999 = 31592366
373 + 31591993 = 31592366
409 + 31591957 = 31592366

Showing the first eight; more decompositions exist.
