Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31478926, here are decompositions:

359 + 31478567 = 31478926
443 + 31478483 = 31478926
593 + 31478333 = 31478926
599 + 31478327 = 31478926
617 + 31478309 = 31478926
659 + 31478267 = 31478926
797 + 31478129 = 31478926
1019 + 31477907 = 31478926

Showing the first eight; more decompositions exist.
