Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 74420, here are decompositions:

7 + 74413 = 74420
37 + 74383 = 74420
43 + 74377 = 74420
67 + 74353 = 74420
97 + 74323 = 74420
103 + 74317 = 74420
109 + 74311 = 74420
127 + 74293 = 74420

Showing the first eight; more decompositions exist.
