Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75390, here are decompositions:

13 + 75377 = 75390
23 + 75367 = 75390
37 + 75353 = 75390
43 + 75347 = 75390
53 + 75337 = 75390
61 + 75329 = 75390
67 + 75323 = 75390
83 + 75307 = 75390

Showing the first eight; more decompositions exist.
