Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742282, here are decompositions:

19 + 8742263 = 8742282
23 + 8742259 = 8742282
89 + 8742193 = 8742282
113 + 8742169 = 8742282
149 + 8742133 = 8742282
179 + 8742103 = 8742282
223 + 8742059 = 8742282
271 + 8742011 = 8742282

Showing the first eight; more decompositions exist.
