Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971730, here are decompositions:

7 + 971723 = 971730
17 + 971713 = 971730
31 + 971699 = 971730
37 + 971693 = 971730
47 + 971683 = 971730
79 + 971651 = 971730
139 + 971591 = 971730
167 + 971563 = 971730

Showing the first eight; more decompositions exist.
