Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474410, here are decompositions:

7 + 31474403 = 31474410
13 + 31474397 = 31474410
47 + 31474363 = 31474410
53 + 31474357 = 31474410
59 + 31474351 = 31474410
67 + 31474343 = 31474410
103 + 31474307 = 31474410
109 + 31474301 = 31474410

Showing the first eight; more decompositions exist.
