Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7402, here are decompositions:

53 + 7349 = 7402
71 + 7331 = 7402
149 + 7253 = 7402
173 + 7229 = 7402
191 + 7211 = 7402
251 + 7151 = 7402
281 + 7121 = 7402
293 + 7109 = 7402

Showing the first eight; more decompositions exist.
