Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742258, here are decompositions:

61 + 8742197 = 8742258
71 + 8742187 = 8742258
89 + 8742169 = 8742258
97 + 8742161 = 8742258
101 + 8742157 = 8742258
137 + 8742121 = 8742258
181 + 8742077 = 8742258
191 + 8742067 = 8742258

Showing the first eight; more decompositions exist.
