Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473174, here are decompositions:

11 + 31473163 = 31473174
13 + 31473161 = 31473174
23 + 31473151 = 31473174
67 + 31473107 = 31473174
97 + 31473077 = 31473174
107 + 31473067 = 31473174
113 + 31473061 = 31473174
137 + 31473037 = 31473174

Showing the first eight; more decompositions exist.
