Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582876, here are decompositions:

29 + 31582847 = 31582876
53 + 31582823 = 31582876
137 + 31582739 = 31582876
197 + 31582679 = 31582876
263 + 31582613 = 31582876
317 + 31582559 = 31582876
467 + 31582409 = 31582876
557 + 31582319 = 31582876

Showing the first eight; more decompositions exist.
