Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 972072, here are decompositions:

41 + 972031 = 972072
43 + 972029 = 972072
71 + 972001 = 972072
83 + 971989 = 972072
113 + 971959 = 972072
139 + 971933 = 972072
151 + 971921 = 972072
173 + 971899 = 972072

Showing the first eight; more decompositions exist.
