Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 465438, here are decompositions:

5 + 465433 = 465438
19 + 465419 = 465438
31 + 465407 = 465438
59 + 465379 = 465438
101 + 465337 = 465438
107 + 465331 = 465438
139 + 465299 = 465438
157 + 465281 = 465438

Showing the first eight; more decompositions exist.
