Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971138, here are decompositions:

61 + 971077 = 971138
109 + 971029 = 971138
139 + 970999 = 971138
151 + 970987 = 971138
199 + 970939 = 971138
211 + 970927 = 971138
229 + 970909 = 971138
271 + 970867 = 971138

Showing the first eight; more decompositions exist.
