Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 74820, here are decompositions:

23 + 74797 = 74820
41 + 74779 = 74820
59 + 74761 = 74820
61 + 74759 = 74820
73 + 74747 = 74820
89 + 74731 = 74820
101 + 74719 = 74820
103 + 74717 = 74820

Showing the first eight; more decompositions exist.
