Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744130, here are decompositions:

29 + 8744101 = 8744130
47 + 8744083 = 8744130
67 + 8744063 = 8744130
89 + 8744041 = 8744130
97 + 8744033 = 8744130
107 + 8744023 = 8744130
127 + 8744003 = 8744130
139 + 8743991 = 8744130

Showing the first eight; more decompositions exist.
