Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8450, here are decompositions:

3 + 8447 = 8450
7 + 8443 = 8450
19 + 8431 = 8450
31 + 8419 = 8450
61 + 8389 = 8450
73 + 8377 = 8450
97 + 8353 = 8450
139 + 8311 = 8450

Showing the first eight; more decompositions exist.
