Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7480, here are decompositions:

3 + 7477 = 7480
23 + 7457 = 7480
29 + 7451 = 7480
47 + 7433 = 7480
131 + 7349 = 7480
149 + 7331 = 7480
173 + 7307 = 7480
197 + 7283 = 7480

Showing the first eight; more decompositions exist.
