Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527884, here are decompositions:

67 + 31527817 = 31527884
97 + 31527787 = 31527884
103 + 31527781 = 31527884
181 + 31527703 = 31527884
307 + 31527577 = 31527884
541 + 31527343 = 31527884
607 + 31527277 = 31527884
631 + 31527253 = 31527884

Showing the first eight; more decompositions exist.
