Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7270, here are decompositions:

17 + 7253 = 7270
23 + 7247 = 7270
41 + 7229 = 7270
59 + 7211 = 7270
83 + 7187 = 7270
149 + 7121 = 7270
167 + 7103 = 7270
191 + 7079 = 7270

Showing the first eight; more decompositions exist.
