Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 469780, here are decompositions:

11 + 469769 = 469780
23 + 469757 = 469780
89 + 469691 = 469780
107 + 469673 = 469780
131 + 469649 = 469780
149 + 469631 = 469780
167 + 469613 = 469780
191 + 469589 = 469780

Showing the first eight; more decompositions exist.
