Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744148, here are decompositions:

5 + 8744143 = 8744148
19 + 8744129 = 8744148
47 + 8744101 = 8744148
67 + 8744081 = 8744148
107 + 8744041 = 8744148
151 + 8743997 = 8744148
157 + 8743991 = 8744148
167 + 8743981 = 8744148

Showing the first eight; more decompositions exist.
