Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742072, here are decompositions:

5 + 8742067 = 8742072
13 + 8742059 = 8742072
61 + 8742011 = 8742072
83 + 8741989 = 8742072
89 + 8741983 = 8742072
139 + 8741933 = 8742072
149 + 8741923 = 8742072
211 + 8741861 = 8742072

Showing the first eight; more decompositions exist.
