Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971972, here are decompositions:

13 + 971959 = 971972
73 + 971899 = 971972
109 + 971863 = 971972
139 + 971833 = 971972
151 + 971821 = 971972
409 + 971563 = 971972
499 + 971473 = 971972
571 + 971401 = 971972

Showing the first eight; more decompositions exist.
