Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7450, here are decompositions:

17 + 7433 = 7450
101 + 7349 = 7450
167 + 7283 = 7450
197 + 7253 = 7450
239 + 7211 = 7450
257 + 7193 = 7450
263 + 7187 = 7450
347 + 7103 = 7450

Showing the first eight; more decompositions exist.
