Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474004, here are decompositions:

13 + 31473991 = 31474004
73 + 31473931 = 31474004
97 + 31473907 = 31474004
103 + 31473901 = 31474004
157 + 31473847 = 31474004
193 + 31473811 = 31474004
223 + 31473781 = 31474004
271 + 31473733 = 31474004

Showing the first eight; more decompositions exist.
