Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742306, here are decompositions:

43 + 8742263 = 8742306
47 + 8742259 = 8742306
109 + 8742197 = 8742306
113 + 8742193 = 8742306
137 + 8742169 = 8742306
149 + 8742157 = 8742306
173 + 8742133 = 8742306
229 + 8742077 = 8742306

Showing the first eight; more decompositions exist.
