Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 74320, here are decompositions:

3 + 74317 = 74320
23 + 74297 = 74320
41 + 74279 = 74320
89 + 74231 = 74320
101 + 74219 = 74320
131 + 74189 = 74320
227 + 74093 = 74320
269 + 74051 = 74320

Showing the first eight; more decompositions exist.
