Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582726, here are decompositions:

47 + 31582679 = 31582726
53 + 31582673 = 31582726
59 + 31582667 = 31582726
113 + 31582613 = 31582726
137 + 31582589 = 31582726
167 + 31582559 = 31582726
173 + 31582553 = 31582726
179 + 31582547 = 31582726

Showing the first eight; more decompositions exist.
