Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681450, here are decompositions:

3 + 8681447 = 8681450
73 + 8681377 = 8681450
109 + 8681341 = 8681450
139 + 8681311 = 8681450
163 + 8681287 = 8681450
199 + 8681251 = 8681450
229 + 8681221 = 8681450
373 + 8681077 = 8681450

Showing the first eight; more decompositions exist.
