Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748148, here are decompositions:

5 + 8748143 = 8748148
11 + 8748137 = 8748148
131 + 8748017 = 8748148
137 + 8748011 = 8748148
191 + 8747957 = 8748148
257 + 8747891 = 8748148
317 + 8747831 = 8748148
359 + 8747789 = 8748148

Showing the first eight; more decompositions exist.
