Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582766, here are decompositions:

37 + 31582729 = 31582766
139 + 31582627 = 31582766
157 + 31582609 = 31582766
277 + 31582489 = 31582766
349 + 31582417 = 31582766
367 + 31582399 = 31582766
433 + 31582333 = 31582766
499 + 31582267 = 31582766

Showing the first eight; more decompositions exist.
