Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478670, here are decompositions:

19 + 478651 = 478670
43 + 478627 = 478670
67 + 478603 = 478670
97 + 478573 = 478670
139 + 478531 = 478670
211 + 478459 = 478670
229 + 478441 = 478670
271 + 478399 = 478670

Showing the first eight; more decompositions exist.
