Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 972986, here are decompositions:

19 + 972967 = 972986
43 + 972943 = 972986
139 + 972847 = 972986
163 + 972823 = 972986
193 + 972793 = 972986
199 + 972787 = 972986
307 + 972679 = 972986
337 + 972649 = 972986

Showing the first eight; more decompositions exist.
