Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533060, here are decompositions:

47 + 31533013 = 31533060
59 + 31533001 = 31533060
61 + 31532999 = 31533060
79 + 31532981 = 31533060
89 + 31532971 = 31533060
101 + 31532959 = 31533060
137 + 31532923 = 31533060
179 + 31532881 = 31533060

Showing the first eight; more decompositions exist.
