Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749234, here are decompositions:

5 + 8749229 = 8749234
71 + 8749163 = 8749234
83 + 8749151 = 8749234
101 + 8749133 = 8749234
107 + 8749127 = 8749234
113 + 8749121 = 8749234
227 + 8749007 = 8749234
233 + 8749001 = 8749234

Showing the first eight; more decompositions exist.
