Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 469838, here are decompositions:

37 + 469801 = 469838
151 + 469687 = 469838
181 + 469657 = 469838
211 + 469627 = 469838
277 + 469561 = 469838
337 + 469501 = 469838
409 + 469429 = 469838
487 + 469351 = 469838

Showing the first eight; more decompositions exist.
