Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473998, here are decompositions:

7 + 31473991 = 31473998
67 + 31473931 = 31473998
97 + 31473901 = 31473998
151 + 31473847 = 31473998
541 + 31473457 = 31473998
601 + 31473397 = 31473998
757 + 31473241 = 31473998
811 + 31473187 = 31473998

Showing the first eight; more decompositions exist.
