Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545060, here are decompositions:

11 + 31545049 = 31545060
37 + 31545023 = 31545060
59 + 31545001 = 31545060
97 + 31544963 = 31545060
137 + 31544923 = 31545060
181 + 31544879 = 31545060
233 + 31544827 = 31545060
241 + 31544819 = 31545060

Showing the first eight; more decompositions exist.
