Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 547438, here are decompositions:

41 + 547397 = 547438
137 + 547301 = 547438
167 + 547271 = 547438
197 + 547241 = 547438
317 + 547121 = 547438
401 + 547037 = 547438
431 + 547007 = 547438
461 + 546977 = 547438

Showing the first eight; more decompositions exist.
