Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520060, here are decompositions:

31 + 31520029 = 31520060
43 + 31520017 = 31520060
73 + 31519987 = 31520060
109 + 31519951 = 31520060
127 + 31519933 = 31520060
151 + 31519909 = 31520060
223 + 31519837 = 31520060
277 + 31519783 = 31520060

Showing the first eight; more decompositions exist.
