Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31557060, here are decompositions:

37 + 31557023 = 31557060
47 + 31557013 = 31557060
53 + 31557007 = 31557060
103 + 31556957 = 31557060
137 + 31556923 = 31557060
149 + 31556911 = 31557060
151 + 31556909 = 31557060
191 + 31556869 = 31557060

Showing the first eight; more decompositions exist.
