Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473258, here are decompositions:

7 + 31473251 = 31473258
17 + 31473241 = 31473258
41 + 31473217 = 31473258
67 + 31473191 = 31473258
71 + 31473187 = 31473258
97 + 31473161 = 31473258
107 + 31473151 = 31473258
149 + 31473109 = 31473258

Showing the first eight; more decompositions exist.
