Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747522, here are decompositions:

103 + 8747419 = 8747522
193 + 8747329 = 8747522
271 + 8747251 = 8747522
331 + 8747191 = 8747522
439 + 8747083 = 8747522
523 + 8746999 = 8747522
601 + 8746921 = 8747522
643 + 8746879 = 8747522

Showing the first eight; more decompositions exist.
