Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 469778, here are decompositions:

31 + 469747 = 469778
61 + 469717 = 469778
151 + 469627 = 469778
277 + 469501 = 469778
349 + 469429 = 469778
367 + 469411 = 469778
409 + 469369 = 469778
457 + 469321 = 469778

Showing the first eight; more decompositions exist.
