Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474086, here are decompositions:

13 + 31474073 = 31474086
29 + 31474057 = 31474086
43 + 31474043 = 31474086
53 + 31474033 = 31474086
79 + 31474007 = 31474086
109 + 31473977 = 31474086
179 + 31473907 = 31474086
199 + 31473887 = 31474086

Showing the first eight; more decompositions exist.
