Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749030, here are decompositions:

11 + 8749019 = 8749030
23 + 8749007 = 8749030
29 + 8749001 = 8749030
41 + 8748989 = 8749030
137 + 8748893 = 8749030
149 + 8748881 = 8749030
263 + 8748767 = 8749030
317 + 8748713 = 8749030

Showing the first eight; more decompositions exist.
