Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467510, here are decompositions:

7 + 31467503 = 31467510
13 + 31467497 = 31467510
29 + 31467481 = 31467510
43 + 31467467 = 31467510
73 + 31467437 = 31467510
79 + 31467431 = 31467510
163 + 31467347 = 31467510
181 + 31467329 = 31467510

Showing the first eight; more decompositions exist.
