Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 472778, here are decompositions:

37 + 472741 = 472778
67 + 472711 = 472778
109 + 472669 = 472778
139 + 472639 = 472778
181 + 472597 = 472778
367 + 472411 = 472778
379 + 472399 = 472778
409 + 472369 = 472778

Showing the first eight; more decompositions exist.
