Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971844, here are decompositions:

11 + 971833 = 971844
23 + 971821 = 971844
61 + 971783 = 971844
131 + 971713 = 971844
151 + 971693 = 971844
191 + 971653 = 971844
193 + 971651 = 971844
281 + 971563 = 971844

Showing the first eight; more decompositions exist.
