Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574376, here are decompositions:

7 + 31574369 = 31574376
13 + 31574363 = 31574376
47 + 31574329 = 31574376
73 + 31574303 = 31574376
79 + 31574297 = 31574376
173 + 31574203 = 31574376
269 + 31574107 = 31574376
277 + 31574099 = 31574376

Showing the first eight; more decompositions exist.
