Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64438, here are decompositions:

5 + 64433 = 64438
137 + 64301 = 64438
167 + 64271 = 64438
251 + 64187 = 64438
281 + 64157 = 64438
347 + 64091 = 64438
401 + 64037 = 64438
419 + 64019 = 64438

Showing the first eight; more decompositions exist.
