Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75442, here are decompositions:

5 + 75437 = 75442
11 + 75431 = 75442
41 + 75401 = 75442
53 + 75389 = 75442
89 + 75353 = 75442
113 + 75329 = 75442
173 + 75269 = 75442
233 + 75209 = 75442

Showing the first eight; more decompositions exist.
