Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574382, here are decompositions:

13 + 31574369 = 31574382
19 + 31574363 = 31574382
53 + 31574329 = 31574382
79 + 31574303 = 31574382
149 + 31574233 = 31574382
179 + 31574203 = 31574382
181 + 31574201 = 31574382
251 + 31574131 = 31574382

Showing the first eight; more decompositions exist.
