Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582346, here are decompositions:

13 + 31582333 = 31582346
79 + 31582267 = 31582346
97 + 31582249 = 31582346
139 + 31582207 = 31582346
163 + 31582183 = 31582346
349 + 31581997 = 31582346
373 + 31581973 = 31582346
457 + 31581889 = 31582346

Showing the first eight; more decompositions exist.
