Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 464438, here are decompositions:

19 + 464419 = 464438
67 + 464371 = 464438
127 + 464311 = 464438
157 + 464281 = 464438
181 + 464257 = 464438
241 + 464197 = 464438
307 + 464131 = 464438
349 + 464089 = 464438

Showing the first eight; more decompositions exist.
