Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7258, here are decompositions:

5 + 7253 = 7258
11 + 7247 = 7258
29 + 7229 = 7258
47 + 7211 = 7258
71 + 7187 = 7258
107 + 7151 = 7258
131 + 7127 = 7258
137 + 7121 = 7258

Showing the first eight; more decompositions exist.
