Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473796, here are decompositions:

17 + 31473779 = 31473796
89 + 31473707 = 31473796
197 + 31473599 = 31473796
317 + 31473479 = 31473796
359 + 31473437 = 31473796
383 + 31473413 = 31473796
587 + 31473209 = 31473796
593 + 31473203 = 31473796

Showing the first eight; more decompositions exist.
