Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75450, here are decompositions:

13 + 75437 = 75450
19 + 75431 = 75450
43 + 75407 = 75450
47 + 75403 = 75450
59 + 75391 = 75450
61 + 75389 = 75450
73 + 75377 = 75450
83 + 75367 = 75450

Showing the first eight; more decompositions exist.
