Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473264, here are decompositions:

13 + 31473251 = 31473264
23 + 31473241 = 31473264
47 + 31473217 = 31473264
61 + 31473203 = 31473264
73 + 31473191 = 31473264
101 + 31473163 = 31473264
103 + 31473161 = 31473264
113 + 31473151 = 31473264

Showing the first eight; more decompositions exist.
