Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748156, here are decompositions:

13 + 8748143 = 8748156
19 + 8748137 = 8748156
47 + 8748109 = 8748156
59 + 8748097 = 8748156
113 + 8748043 = 8748156
139 + 8748017 = 8748156
199 + 8747957 = 8748156
223 + 8747933 = 8748156

Showing the first eight; more decompositions exist.
