Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7390, here are decompositions:

41 + 7349 = 7390
59 + 7331 = 7390
83 + 7307 = 7390
107 + 7283 = 7390
137 + 7253 = 7390
179 + 7211 = 7390
197 + 7193 = 7390
239 + 7151 = 7390

Showing the first eight; more decompositions exist.
