Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75440, here are decompositions:

3 + 75437 = 75440
37 + 75403 = 75440
73 + 75367 = 75440
103 + 75337 = 75440
151 + 75289 = 75440
163 + 75277 = 75440
223 + 75217 = 75440
229 + 75211 = 75440

Showing the first eight; more decompositions exist.
