Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527876, here are decompositions:

47 + 31527829 = 31527876
59 + 31527817 = 31527876
89 + 31527787 = 31527876
167 + 31527709 = 31527876
173 + 31527703 = 31527876
179 + 31527697 = 31527876
199 + 31527677 = 31527876
293 + 31527583 = 31527876

Showing the first eight; more decompositions exist.
