Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473874, here are decompositions:

11 + 31473863 = 31473874
167 + 31473707 = 31473874
281 + 31473593 = 31473874
293 + 31473581 = 31473874
461 + 31473413 = 31473874
683 + 31473191 = 31473874
701 + 31473173 = 31473874
797 + 31473077 = 31473874

Showing the first eight; more decompositions exist.
