Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971830, here are decompositions:

47 + 971783 = 971830
71 + 971759 = 971830
107 + 971723 = 971830
131 + 971699 = 971830
137 + 971693 = 971830
179 + 971651 = 971830
191 + 971639 = 971830
239 + 971591 = 971830

Showing the first eight; more decompositions exist.
