Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473470, here are decompositions:

13 + 31473457 = 31473470
73 + 31473397 = 31473470
139 + 31473331 = 31473470
157 + 31473313 = 31473470
229 + 31473241 = 31473470
283 + 31473187 = 31473470
307 + 31473163 = 31473470
409 + 31473061 = 31473470

Showing the first eight; more decompositions exist.
