Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47438, here are decompositions:

7 + 47431 = 47438
19 + 47419 = 47438
31 + 47407 = 47438
151 + 47287 = 47438
277 + 47161 = 47438
379 + 47059 = 47438
397 + 47041 = 47438
421 + 47017 = 47438

Showing the first eight; more decompositions exist.
