Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 972120, here are decompositions:

7 + 972113 = 972120
29 + 972091 = 972120
41 + 972079 = 972120
73 + 972047 = 972120
89 + 972031 = 972120
103 + 972017 = 972120
131 + 971989 = 972120
139 + 971981 = 972120

Showing the first eight; more decompositions exist.
