Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528376, here are decompositions:

3 + 31528373 = 31528376
13 + 31528363 = 31528376
97 + 31528279 = 31528376
109 + 31528267 = 31528376
163 + 31528213 = 31528376
283 + 31528093 = 31528376
307 + 31528069 = 31528376
379 + 31527997 = 31528376

Showing the first eight; more decompositions exist.
