Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749258, here are decompositions:

29 + 8749229 = 8749258
59 + 8749199 = 8749258
107 + 8749151 = 8749258
131 + 8749127 = 8749258
137 + 8749121 = 8749258
239 + 8749019 = 8749258
251 + 8749007 = 8749258
257 + 8749001 = 8749258

Showing the first eight; more decompositions exist.
