Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478830, here are decompositions:

7 + 478823 = 478830
17 + 478813 = 478830
19 + 478811 = 478830
29 + 478801 = 478830
43 + 478787 = 478830
61 + 478769 = 478830
67 + 478763 = 478830
83 + 478747 = 478830

Showing the first eight; more decompositions exist.
