Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473984, here are decompositions:

7 + 31473977 = 31473984
13 + 31473971 = 31473984
53 + 31473931 = 31473984
67 + 31473917 = 31473984
83 + 31473901 = 31473984
97 + 31473887 = 31473984
137 + 31473847 = 31473984
173 + 31473811 = 31473984

Showing the first eight; more decompositions exist.
