Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 473640, here are decompositions:

7 + 473633 = 473640
23 + 473617 = 473640
29 + 473611 = 473640
43 + 473597 = 473640
61 + 473579 = 473640
107 + 473533 = 473640
109 + 473531 = 473640
113 + 473527 = 473640

Showing the first eight; more decompositions exist.
