Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473262, here are decompositions:

11 + 31473251 = 31473262
53 + 31473209 = 31473262
59 + 31473203 = 31473262
71 + 31473191 = 31473262
89 + 31473173 = 31473262
101 + 31473161 = 31473262
179 + 31473083 = 31473262
383 + 31472879 = 31473262

Showing the first eight; more decompositions exist.
