Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574374, here are decompositions:

5 + 31574369 = 31574374
11 + 31574363 = 31574374
47 + 31574327 = 31574374
71 + 31574303 = 31574374
113 + 31574261 = 31574374
173 + 31574201 = 31574374
281 + 31574093 = 31574374
353 + 31574021 = 31574374

Showing the first eight; more decompositions exist.
