Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947400, here are decompositions:

11 + 947389 = 947400
17 + 947383 = 947400
19 + 947381 = 947400
23 + 947377 = 947400
31 + 947369 = 947400
43 + 947357 = 947400
59 + 947341 = 947400
73 + 947327 = 947400

Showing the first eight; more decompositions exist.
