Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7290, here are decompositions:

7 + 7283 = 7290
37 + 7253 = 7290
43 + 7247 = 7290
47 + 7243 = 7290
53 + 7237 = 7290
61 + 7229 = 7290
71 + 7219 = 7290
79 + 7211 = 7290

Showing the first eight; more decompositions exist.
