Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474364, here are decompositions:

7 + 31474357 = 31474364
13 + 31474351 = 31474364
73 + 31474291 = 31474364
151 + 31474213 = 31474364
193 + 31474171 = 31474364
223 + 31474141 = 31474364
307 + 31474057 = 31474364
331 + 31474033 = 31474364

Showing the first eight; more decompositions exist.
