Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473924, here are decompositions:

7 + 31473917 = 31473924
17 + 31473907 = 31473924
23 + 31473901 = 31473924
37 + 31473887 = 31473924
61 + 31473863 = 31473924
113 + 31473811 = 31473924
191 + 31473733 = 31473924
331 + 31473593 = 31473924

Showing the first eight; more decompositions exist.
