Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7428, here are decompositions:

11 + 7417 = 7428
17 + 7411 = 7428
59 + 7369 = 7428
79 + 7349 = 7428
97 + 7331 = 7428
107 + 7321 = 7428
131 + 7297 = 7428
181 + 7247 = 7428

Showing the first eight; more decompositions exist.
