Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657832, here are decompositions:

5 + 8657827 = 8657832
31 + 8657801 = 8657832
61 + 8657771 = 8657832
101 + 8657731 = 8657832
109 + 8657723 = 8657832
151 + 8657681 = 8657832
181 + 8657651 = 8657832
193 + 8657639 = 8657832

Showing the first eight; more decompositions exist.
