Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473926, here are decompositions:

19 + 31473907 = 31473926
79 + 31473847 = 31473926
193 + 31473733 = 31473926
223 + 31473703 = 31473926
397 + 31473529 = 31473926
439 + 31473487 = 31473926
613 + 31473313 = 31473926
643 + 31473283 = 31473926

Showing the first eight; more decompositions exist.
