Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559060, here are decompositions:

67 + 31558993 = 31559060
97 + 31558963 = 31559060
103 + 31558957 = 31559060
163 + 31558897 = 31559060
229 + 31558831 = 31559060
241 + 31558819 = 31559060
271 + 31558789 = 31559060
331 + 31558729 = 31559060

Showing the first eight; more decompositions exist.
