Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474060, here are decompositions:

3 + 31474057 = 31474060
17 + 31474043 = 31474060
53 + 31474007 = 31474060
83 + 31473977 = 31474060
89 + 31473971 = 31474060
173 + 31473887 = 31474060
197 + 31473863 = 31474060
251 + 31473809 = 31474060

Showing the first eight; more decompositions exist.
