Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474374, here are decompositions:

11 + 31474363 = 31474374
17 + 31474357 = 31474374
23 + 31474351 = 31474374
31 + 31474343 = 31474374
67 + 31474307 = 31474374
73 + 31474301 = 31474374
83 + 31474291 = 31474374
157 + 31474217 = 31474374

Showing the first eight; more decompositions exist.
