Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473186, here are decompositions:

13 + 31473173 = 31473186
23 + 31473163 = 31473186
79 + 31473107 = 31473186
103 + 31473083 = 31473186
109 + 31473077 = 31473186
149 + 31473037 = 31473186
223 + 31472963 = 31473186
257 + 31472929 = 31473186

Showing the first eight; more decompositions exist.
