Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 972158, here are decompositions:

37 + 972121 = 972158
67 + 972091 = 972158
79 + 972079 = 972158
127 + 972031 = 972158
157 + 972001 = 972158
181 + 971977 = 972158
199 + 971959 = 972158
241 + 971917 = 972158

Showing the first eight; more decompositions exist.
