Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947492, here are decompositions:

43 + 947449 = 947492
61 + 947431 = 947492
79 + 947413 = 947492
103 + 947389 = 947492
109 + 947383 = 947492
151 + 947341 = 947492
193 + 947299 = 947492
229 + 947263 = 947492

Showing the first eight; more decompositions exist.
