Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7240, here are decompositions:

3 + 7237 = 7240
11 + 7229 = 7240
29 + 7211 = 7240
47 + 7193 = 7240
53 + 7187 = 7240
89 + 7151 = 7240
113 + 7127 = 7240
131 + 7109 = 7240

Showing the first eight; more decompositions exist.
