Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467498, here are decompositions:

17 + 31467481 = 31467498
31 + 31467467 = 31467498
61 + 31467437 = 31467498
67 + 31467431 = 31467498
79 + 31467419 = 31467498
109 + 31467389 = 31467498
131 + 31467367 = 31467498
151 + 31467347 = 31467498

Showing the first eight; more decompositions exist.
