Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7300, here are decompositions:

3 + 7297 = 7300
17 + 7283 = 7300
47 + 7253 = 7300
53 + 7247 = 7300
71 + 7229 = 7300
89 + 7211 = 7300
107 + 7193 = 7300
113 + 7187 = 7300

Showing the first eight; more decompositions exist.
