Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597234, here are decompositions:

3 + 31597231 = 31597234
83 + 31597151 = 31597234
107 + 31597127 = 31597234
113 + 31597121 = 31597234
191 + 31597043 = 31597234
257 + 31596977 = 31597234
311 + 31596923 = 31597234
353 + 31596881 = 31597234

Showing the first eight; more decompositions exist.
