Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749282, here are decompositions:

53 + 8749229 = 8749282
83 + 8749199 = 8749282
131 + 8749151 = 8749282
149 + 8749133 = 8749282
233 + 8749049 = 8749282
263 + 8749019 = 8749282
281 + 8749001 = 8749282
293 + 8748989 = 8749282

Showing the first eight; more decompositions exist.
