Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75428, here are decompositions:

37 + 75391 = 75428
61 + 75367 = 75428
139 + 75289 = 75428
151 + 75277 = 75428
211 + 75217 = 75428
349 + 75079 = 75428
487 + 74941 = 75428
499 + 74929 = 75428

Showing the first eight; more decompositions exist.
