Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749120, here are decompositions:

71 + 8749049 = 8749120
101 + 8749019 = 8749120
113 + 8749007 = 8749120
131 + 8748989 = 8749120
167 + 8748953 = 8749120
227 + 8748893 = 8749120
239 + 8748881 = 8749120
293 + 8748827 = 8749120

Showing the first eight; more decompositions exist.
