Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744172, here are decompositions:

23 + 8744149 = 8744172
29 + 8744143 = 8744172
43 + 8744129 = 8744172
71 + 8744101 = 8744172
89 + 8744083 = 8744172
109 + 8744063 = 8744172
131 + 8744041 = 8744172
139 + 8744033 = 8744172

Showing the first eight; more decompositions exist.
