Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742012, here are decompositions:

23 + 8741989 = 8742012
29 + 8741983 = 8742012
61 + 8741951 = 8742012
79 + 8741933 = 8742012
89 + 8741923 = 8742012
101 + 8741911 = 8742012
151 + 8741861 = 8742012
173 + 8741839 = 8742012

Showing the first eight; more decompositions exist.
