Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 472808, here are decompositions:

67 + 472741 = 472808
97 + 472711 = 472808
139 + 472669 = 472808
211 + 472597 = 472808
331 + 472477 = 472808
397 + 472411 = 472808
409 + 472399 = 472808
439 + 472369 = 472808

Showing the first eight; more decompositions exist.
