Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592158, here are decompositions:

29 + 31592129 = 31592158
107 + 31592051 = 31592158
179 + 31591979 = 31592158
419 + 31591739 = 31592158
491 + 31591667 = 31592158
509 + 31591649 = 31592158
557 + 31591601 = 31592158
641 + 31591517 = 31592158

Showing the first eight; more decompositions exist.
