Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474370, here are decompositions:

7 + 31474363 = 31474370
13 + 31474357 = 31474370
19 + 31474351 = 31474370
79 + 31474291 = 31474370
157 + 31474213 = 31474370
199 + 31474171 = 31474370
229 + 31474141 = 31474370
241 + 31474129 = 31474370

Showing the first eight; more decompositions exist.
