Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749122, here are decompositions:

73 + 8749049 = 8749122
103 + 8749019 = 8749122
131 + 8748991 = 8749122
149 + 8748973 = 8749122
229 + 8748893 = 8749122
233 + 8748889 = 8749122
241 + 8748881 = 8749122
269 + 8748853 = 8749122

Showing the first eight; more decompositions exist.
