Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947578, here are decompositions:

17 + 947561 = 947578
167 + 947411 = 947578
197 + 947381 = 947578
227 + 947351 = 947578
251 + 947327 = 947578
449 + 947129 = 947578
617 + 946961 = 947578
647 + 946931 = 947578

Showing the first eight; more decompositions exist.
