Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 972140, here are decompositions:

3 + 972137 = 972140
7 + 972133 = 972140
19 + 972121 = 972140
61 + 972079 = 972140
109 + 972031 = 972140
139 + 972001 = 972140
151 + 971989 = 972140
163 + 971977 = 972140

Showing the first eight; more decompositions exist.
