Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540260, here are decompositions:

19 + 31540241 = 31540260
43 + 31540217 = 31540260
47 + 31540213 = 31540260
53 + 31540207 = 31540260
71 + 31540189 = 31540260
79 + 31540181 = 31540260
97 + 31540163 = 31540260
113 + 31540147 = 31540260

Showing the first eight; more decompositions exist.
