Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474256, here are decompositions:

3 + 31474253 = 31474256
7 + 31474249 = 31474256
43 + 31474213 = 31474256
127 + 31474129 = 31474256
199 + 31474057 = 31474256
223 + 31474033 = 31474256
349 + 31473907 = 31474256
409 + 31473847 = 31474256

Showing the first eight; more decompositions exist.
