Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742318, here are decompositions:

5 + 8742313 = 8742318
59 + 8742259 = 8742318
131 + 8742187 = 8742318
149 + 8742169 = 8742318
157 + 8742161 = 8742318
197 + 8742121 = 8742318
241 + 8742077 = 8742318
251 + 8742067 = 8742318

Showing the first eight; more decompositions exist.
