Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473958, here are decompositions:

41 + 31473917 = 31473958
71 + 31473887 = 31473958
149 + 31473809 = 31473958
179 + 31473779 = 31473958
251 + 31473707 = 31473958
359 + 31473599 = 31473958
479 + 31473479 = 31473958
521 + 31473437 = 31473958

Showing the first eight; more decompositions exist.
