Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592146, here are decompositions:

17 + 31592129 = 31592146
23 + 31592123 = 31592146
107 + 31592039 = 31592146
149 + 31591997 = 31592146
167 + 31591979 = 31592146
233 + 31591913 = 31592146
353 + 31591793 = 31592146
479 + 31591667 = 31592146

Showing the first eight; more decompositions exist.
