Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467494, here are decompositions:

13 + 31467481 = 31467494
61 + 31467433 = 31467494
127 + 31467367 = 31467494
193 + 31467301 = 31467494
313 + 31467181 = 31467494
337 + 31467157 = 31467494
367 + 31467127 = 31467494
601 + 31466893 = 31467494

Showing the first eight; more decompositions exist.
