Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971740, here are decompositions:

17 + 971723 = 971740
41 + 971699 = 971740
47 + 971693 = 971740
89 + 971651 = 971740
101 + 971639 = 971740
149 + 971591 = 971740
179 + 971561 = 971740
191 + 971549 = 971740

Showing the first eight; more decompositions exist.
