Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473048, here are decompositions:

7 + 31473041 = 31473048
11 + 31473037 = 31473048
17 + 31473031 = 31473048
157 + 31472891 = 31473048
181 + 31472867 = 31473048
197 + 31472851 = 31473048
199 + 31472849 = 31473048
241 + 31472807 = 31473048

Showing the first eight; more decompositions exist.
