Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 74660, here are decompositions:

7 + 74653 = 74660
37 + 74623 = 74660
73 + 74587 = 74660
109 + 74551 = 74660
139 + 74521 = 74660
151 + 74509 = 74660
211 + 74449 = 74660
241 + 74419 = 74660

Showing the first eight; more decompositions exist.
