Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582376, here are decompositions:

43 + 31582333 = 31582376
109 + 31582267 = 31582376
127 + 31582249 = 31582376
193 + 31582183 = 31582376
283 + 31582093 = 31582376
349 + 31582027 = 31582376
373 + 31582003 = 31582376
379 + 31581997 = 31582376

Showing the first eight; more decompositions exist.
