Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 472730, here are decompositions:

19 + 472711 = 472730
43 + 472687 = 472730
61 + 472669 = 472730
157 + 472573 = 472730
331 + 472399 = 472730
337 + 472393 = 472730
397 + 472333 = 472730
421 + 472309 = 472730

Showing the first eight; more decompositions exist.
