Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508060, here are decompositions:

43 + 31508017 = 31508060
79 + 31507981 = 31508060
109 + 31507951 = 31508060
139 + 31507921 = 31508060
163 + 31507897 = 31508060
223 + 31507837 = 31508060
271 + 31507789 = 31508060
307 + 31507753 = 31508060

Showing the first eight; more decompositions exist.
