Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467484, here are decompositions:

3 + 31467481 = 31467484
17 + 31467467 = 31467484
47 + 31467437 = 31467484
53 + 31467431 = 31467484
137 + 31467347 = 31467484
173 + 31467311 = 31467484
233 + 31467251 = 31467484
281 + 31467203 = 31467484

Showing the first eight; more decompositions exist.
