Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719236, here are decompositions:

13 + 8719223 = 8719236
17 + 8719219 = 8719236
23 + 8719213 = 8719236
37 + 8719199 = 8719236
59 + 8719177 = 8719236
73 + 8719163 = 8719236
103 + 8719133 = 8719236
109 + 8719127 = 8719236

Showing the first eight; more decompositions exist.
