Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947438, here are decompositions:

7 + 947431 = 947438
31 + 947407 = 947438
61 + 947377 = 947438
97 + 947341 = 947438
139 + 947299 = 947438
199 + 947239 = 947438
241 + 947197 = 947438
577 + 946861 = 947438

Showing the first eight; more decompositions exist.
