Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478772, here are decompositions:

3 + 478769 = 478772
31 + 478741 = 478772
43 + 478729 = 478772
61 + 478711 = 478772
193 + 478579 = 478772
199 + 478573 = 478772
241 + 478531 = 478772
313 + 478459 = 478772

Showing the first eight; more decompositions exist.
