Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8607844, here are decompositions:

23 + 8607821 = 8607844
41 + 8607803 = 8607844
107 + 8607737 = 8607844
131 + 8607713 = 8607844
191 + 8607653 = 8607844
257 + 8607587 = 8607844
281 + 8607563 = 8607844
431 + 8607413 = 8607844

Showing the first eight; more decompositions exist.
