Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474078, here are decompositions:

5 + 31474073 = 31474078
17 + 31474061 = 31474078
71 + 31474007 = 31474078
101 + 31473977 = 31474078
107 + 31473971 = 31474078
191 + 31473887 = 31474078
239 + 31473839 = 31474078
269 + 31473809 = 31474078

Showing the first eight; more decompositions exist.
