Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592182, here are decompositions:

23 + 31592159 = 31592182
53 + 31592129 = 31592182
59 + 31592123 = 31592182
131 + 31592051 = 31592182
269 + 31591913 = 31592182
389 + 31591793 = 31592182
431 + 31591751 = 31592182
443 + 31591739 = 31592182

Showing the first eight; more decompositions exist.
