Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947518, here are decompositions:

17 + 947501 = 947518
101 + 947417 = 947518
107 + 947411 = 947518
137 + 947381 = 947518
149 + 947369 = 947518
167 + 947351 = 947518
191 + 947327 = 947518
347 + 947171 = 947518

Showing the first eight; more decompositions exist.
