Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467486, here are decompositions:

5 + 31467481 = 31467486
19 + 31467467 = 31467486
53 + 31467433 = 31467486
67 + 31467419 = 31467486
97 + 31467389 = 31467486
139 + 31467347 = 31467486
157 + 31467329 = 31467486
227 + 31467259 = 31467486

Showing the first eight; more decompositions exist.
