Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749228, here are decompositions:

29 + 8749199 = 8749228
101 + 8749127 = 8749228
107 + 8749121 = 8749228
179 + 8749049 = 8749228
227 + 8749001 = 8749228
239 + 8748989 = 8749228
347 + 8748881 = 8749228
401 + 8748827 = 8749228

Showing the first eight; more decompositions exist.
