Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474084, here are decompositions:

11 + 31474073 = 31474084
23 + 31474061 = 31474084
41 + 31474043 = 31474084
107 + 31473977 = 31474084
113 + 31473971 = 31474084
167 + 31473917 = 31474084
197 + 31473887 = 31474084
491 + 31473593 = 31474084

Showing the first eight; more decompositions exist.
