Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474018, here are decompositions:

11 + 31474007 = 31474018
41 + 31473977 = 31474018
47 + 31473971 = 31474018
101 + 31473917 = 31474018
131 + 31473887 = 31474018
179 + 31473839 = 31474018
239 + 31473779 = 31474018
311 + 31473707 = 31474018

Showing the first eight; more decompositions exist.
