Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474110, here are decompositions:

37 + 31474073 = 31474110
53 + 31474057 = 31474110
67 + 31474043 = 31474110
103 + 31474007 = 31474110
139 + 31473971 = 31474110
179 + 31473931 = 31474110
193 + 31473917 = 31474110
223 + 31473887 = 31474110

Showing the first eight; more decompositions exist.
