Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473348, here are decompositions:

17 + 31473331 = 31473348
97 + 31473251 = 31473348
107 + 31473241 = 31473348
131 + 31473217 = 31473348
139 + 31473209 = 31473348
157 + 31473191 = 31473348
197 + 31473151 = 31473348
239 + 31473109 = 31473348

Showing the first eight; more decompositions exist.
