Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596120, here are decompositions:

53 + 31596067 = 31596120
71 + 31596049 = 31596120
79 + 31596041 = 31596120
113 + 31596007 = 31596120
131 + 31595989 = 31596120
137 + 31595983 = 31596120
151 + 31595969 = 31596120
191 + 31595929 = 31596120

Showing the first eight; more decompositions exist.
