Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047620, here are decompositions:

31 + 1047589 = 1047620
61 + 1047559 = 1047620
109 + 1047511 = 1047620
151 + 1047469 = 1047620
229 + 1047391 = 1047620
241 + 1047379 = 1047620
307 + 1047313 = 1047620
313 + 1047307 = 1047620

Showing the first eight; more decompositions exist.
