Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 972156, here are decompositions:

19 + 972137 = 972156
23 + 972133 = 972156
37 + 972119 = 972156
43 + 972113 = 972156
109 + 972047 = 972156
127 + 972029 = 972156
139 + 972017 = 972156
167 + 971989 = 972156

Showing the first eight; more decompositions exist.
