Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 76438, here are decompositions:

17 + 76421 = 76438
59 + 76379 = 76438
71 + 76367 = 76438
149 + 76289 = 76438
179 + 76259 = 76438
281 + 76157 = 76438
347 + 76091 = 76438
359 + 76079 = 76438

Showing the first eight; more decompositions exist.
