Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467420, here are decompositions:

31 + 31467389 = 31467420
53 + 31467367 = 31467420
73 + 31467347 = 31467420
109 + 31467311 = 31467420
191 + 31467229 = 31467420
239 + 31467181 = 31467420
251 + 31467169 = 31467420
263 + 31467157 = 31467420

Showing the first eight; more decompositions exist.
