Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473960, here are decompositions:

29 + 31473931 = 31473960
43 + 31473917 = 31473960
53 + 31473907 = 31473960
59 + 31473901 = 31473960
73 + 31473887 = 31473960
97 + 31473863 = 31473960
113 + 31473847 = 31473960
149 + 31473811 = 31473960

Showing the first eight; more decompositions exist.
