Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742036, here are decompositions:

47 + 8741989 = 8742036
53 + 8741983 = 8742036
59 + 8741977 = 8742036
89 + 8741947 = 8742036
103 + 8741933 = 8742036
113 + 8741923 = 8742036
197 + 8741839 = 8742036
223 + 8741813 = 8742036

Showing the first eight; more decompositions exist.
