Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 469830, here are decompositions:

7 + 469823 = 469830
19 + 469811 = 469830
29 + 469801 = 469830
37 + 469793 = 469830
43 + 469787 = 469830
61 + 469769 = 469830
73 + 469757 = 469830
83 + 469747 = 469830

Showing the first eight; more decompositions exist.
