Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473968, here are decompositions:

37 + 31473931 = 31473968
61 + 31473907 = 31473968
67 + 31473901 = 31473968
157 + 31473811 = 31473968
439 + 31473529 = 31473968
571 + 31473397 = 31473968
727 + 31473241 = 31473968
751 + 31473217 = 31473968

Showing the first eight; more decompositions exist.
