Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740288, here are decompositions:

101 + 8740187 = 8740288
131 + 8740157 = 8740288
149 + 8740139 = 8740288
191 + 8740097 = 8740288
251 + 8740037 = 8740288
419 + 8739869 = 8740288
461 + 8739827 = 8740288
467 + 8739821 = 8740288

Showing the first eight; more decompositions exist.
