Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742288, here are decompositions:

29 + 8742259 = 8742288
101 + 8742187 = 8742288
127 + 8742161 = 8742288
131 + 8742157 = 8742288
167 + 8742121 = 8742288
211 + 8742077 = 8742288
229 + 8742059 = 8742288
251 + 8742037 = 8742288

Showing the first eight; more decompositions exist.
