Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467460, here are decompositions:

23 + 31467437 = 31467460
29 + 31467431 = 31467460
41 + 31467419 = 31467460
71 + 31467389 = 31467460
113 + 31467347 = 31467460
131 + 31467329 = 31467460
149 + 31467311 = 31467460
257 + 31467203 = 31467460

Showing the first eight; more decompositions exist.
