Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474000, here are decompositions:

23 + 31473977 = 31474000
29 + 31473971 = 31474000
83 + 31473917 = 31474000
113 + 31473887 = 31474000
137 + 31473863 = 31474000
191 + 31473809 = 31474000
293 + 31473707 = 31474000
401 + 31473599 = 31474000

Showing the first eight; more decompositions exist.
