Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529426, here are decompositions:

13 + 31529413 = 31529426
67 + 31529359 = 31529426
73 + 31529353 = 31529426
79 + 31529347 = 31529426
157 + 31529269 = 31529426
277 + 31529149 = 31529426
337 + 31529089 = 31529426
373 + 31529053 = 31529426

Showing the first eight; more decompositions exist.
