Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7438, here are decompositions:

5 + 7433 = 7438
89 + 7349 = 7438
107 + 7331 = 7438
131 + 7307 = 7438
191 + 7247 = 7438
227 + 7211 = 7438
251 + 7187 = 7438
311 + 7127 = 7438

Showing the first eight; more decompositions exist.
