Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8697972, here are decompositions:

5 + 8697967 = 8697972
29 + 8697943 = 8697972
53 + 8697919 = 8697972
71 + 8697901 = 8697972
83 + 8697889 = 8697972
103 + 8697869 = 8697972
113 + 8697859 = 8697972
139 + 8697833 = 8697972

Showing the first eight; more decompositions exist.
