Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527846, here are decompositions:

17 + 31527829 = 31527846
19 + 31527827 = 31527846
29 + 31527817 = 31527846
59 + 31527787 = 31527846
137 + 31527709 = 31527846
149 + 31527697 = 31527846
157 + 31527689 = 31527846
263 + 31527583 = 31527846

Showing the first eight; more decompositions exist.
