Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7420, here are decompositions:

3 + 7417 = 7420
71 + 7349 = 7420
89 + 7331 = 7420
113 + 7307 = 7420
137 + 7283 = 7420
167 + 7253 = 7420
173 + 7247 = 7420
191 + 7229 = 7420

Showing the first eight; more decompositions exist.
