Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747564, here are decompositions:

3 + 8747561 = 8747564
37 + 8747527 = 8747564
157 + 8747407 = 8747564
307 + 8747257 = 8747564
313 + 8747251 = 8747564
373 + 8747191 = 8747564
523 + 8747041 = 8747564
601 + 8746963 = 8747564

Showing the first eight; more decompositions exist.
