Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596260, here are decompositions:

67 + 31596193 = 31596260
97 + 31596163 = 31596260
109 + 31596151 = 31596260
139 + 31596121 = 31596260
193 + 31596067 = 31596260
211 + 31596049 = 31596260
271 + 31595989 = 31596260
277 + 31595983 = 31596260

Showing the first eight; more decompositions exist.
