Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971642, here are decompositions:

3 + 971639 = 971642
73 + 971569 = 971642
79 + 971563 = 971642
151 + 971491 = 971642
163 + 971479 = 971642
223 + 971419 = 971642
241 + 971401 = 971642
271 + 971371 = 971642

Showing the first eight; more decompositions exist.
