Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474354, here are decompositions:

3 + 31474351 = 31474354
11 + 31474343 = 31474354
47 + 31474307 = 31474354
53 + 31474301 = 31474354
101 + 31474253 = 31474354
137 + 31474217 = 31474354
281 + 31474073 = 31474354
293 + 31474061 = 31474354

Showing the first eight; more decompositions exist.
