Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474064, here are decompositions:

3 + 31474061 = 31474064
7 + 31474057 = 31474064
31 + 31474033 = 31474064
73 + 31473991 = 31474064
157 + 31473907 = 31474064
163 + 31473901 = 31474064
283 + 31473781 = 31474064
331 + 31473733 = 31474064

Showing the first eight; more decompositions exist.
