Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574476, here are decompositions:

23 + 31574453 = 31574476
47 + 31574429 = 31574476
107 + 31574369 = 31574476
113 + 31574363 = 31574476
149 + 31574327 = 31574476
173 + 31574303 = 31574476
179 + 31574297 = 31574476
383 + 31574093 = 31574476

Showing the first eight; more decompositions exist.
