Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607060, here are decompositions:

13 + 31607047 = 31607060
97 + 31606963 = 31607060
103 + 31606957 = 31607060
109 + 31606951 = 31607060
157 + 31606903 = 31607060
181 + 31606879 = 31607060
307 + 31606753 = 31607060
349 + 31606711 = 31607060

Showing the first eight; more decompositions exist.
