Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471484, here are decompositions:

3 + 31471481 = 31471484
73 + 31471411 = 31471484
97 + 31471387 = 31471484
127 + 31471357 = 31471484
271 + 31471213 = 31471484
277 + 31471207 = 31471484
313 + 31471171 = 31471484
337 + 31471147 = 31471484

Showing the first eight; more decompositions exist.
