Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540460, here are decompositions:

19 + 31540441 = 31540460
43 + 31540417 = 31540460
97 + 31540363 = 31540460
151 + 31540309 = 31540460
163 + 31540297 = 31540460
199 + 31540261 = 31540460
271 + 31540189 = 31540460
313 + 31540147 = 31540460

Showing the first eight; more decompositions exist.
