Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 74540, here are decompositions:

13 + 74527 = 74540
19 + 74521 = 74540
31 + 74509 = 74540
127 + 74413 = 74540
157 + 74383 = 74540
163 + 74377 = 74540
223 + 74317 = 74540
229 + 74311 = 74540

Showing the first eight; more decompositions exist.
