Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742030, here are decompositions:

19 + 8742011 = 8742030
41 + 8741989 = 8742030
43 + 8741987 = 8742030
47 + 8741983 = 8742030
53 + 8741977 = 8742030
79 + 8741951 = 8742030
83 + 8741947 = 8742030
97 + 8741933 = 8742030

Showing the first eight; more decompositions exist.
