Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7380, here are decompositions:

11 + 7369 = 7380
29 + 7351 = 7380
31 + 7349 = 7380
47 + 7333 = 7380
59 + 7321 = 7380
71 + 7309 = 7380
73 + 7307 = 7380
83 + 7297 = 7380

Showing the first eight; more decompositions exist.
