Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473294, here are decompositions:

11 + 31473283 = 31473294
31 + 31473263 = 31473294
43 + 31473251 = 31473294
53 + 31473241 = 31473294
103 + 31473191 = 31473294
107 + 31473187 = 31473294
131 + 31473163 = 31473294
211 + 31473083 = 31473294

Showing the first eight; more decompositions exist.
