Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749288, here are decompositions:

59 + 8749229 = 8749288
89 + 8749199 = 8749288
137 + 8749151 = 8749288
167 + 8749121 = 8749288
239 + 8749049 = 8749288
269 + 8749019 = 8749288
281 + 8749007 = 8749288
461 + 8748827 = 8749288

Showing the first eight; more decompositions exist.
