Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691824, here are decompositions:

61 + 8691763 = 8691824
73 + 8691751 = 8691824
151 + 8691673 = 8691824
157 + 8691667 = 8691824
181 + 8691643 = 8691824
241 + 8691583 = 8691824
283 + 8691541 = 8691824
373 + 8691451 = 8691824

Showing the first eight; more decompositions exist.
