Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474214, here are decompositions:

43 + 31474171 = 31474214
73 + 31474141 = 31474214
103 + 31474111 = 31474214
157 + 31474057 = 31474214
181 + 31474033 = 31474214
223 + 31473991 = 31474214
283 + 31473931 = 31474214
307 + 31473907 = 31474214

Showing the first eight; more decompositions exist.
