Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527896, here are decompositions:

67 + 31527829 = 31527896
79 + 31527817 = 31527896
109 + 31527787 = 31527896
193 + 31527703 = 31527896
199 + 31527697 = 31527896
313 + 31527583 = 31527896
373 + 31527523 = 31527896
397 + 31527499 = 31527896

Showing the first eight; more decompositions exist.
