Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971800, here are decompositions:

17 + 971783 = 971800
41 + 971759 = 971800
47 + 971753 = 971800
101 + 971699 = 971800
107 + 971693 = 971800
149 + 971651 = 971800
239 + 971561 = 971800
251 + 971549 = 971800

Showing the first eight; more decompositions exist.
