Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473896, here are decompositions:

163 + 31473733 = 31473896
193 + 31473703 = 31473896
313 + 31473583 = 31473896
367 + 31473529 = 31473896
373 + 31473523 = 31473896
409 + 31473487 = 31473896
439 + 31473457 = 31473896
499 + 31473397 = 31473896

Showing the first eight; more decompositions exist.
