Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 74680, here are decompositions:

71 + 74609 = 74680
83 + 74597 = 74680
107 + 74573 = 74680
113 + 74567 = 74680
149 + 74531 = 74680
173 + 74507 = 74680
191 + 74489 = 74680
227 + 74453 = 74680

Showing the first eight; more decompositions exist.
