Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592112, here are decompositions:

59 + 31592053 = 31592112
61 + 31592051 = 31592112
73 + 31592039 = 31592112
113 + 31591999 = 31592112
199 + 31591913 = 31592112
239 + 31591873 = 31592112
269 + 31591843 = 31592112
373 + 31591739 = 31592112

Showing the first eight; more decompositions exist.
