Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75420, here are decompositions:

13 + 75407 = 75420
17 + 75403 = 75420
19 + 75401 = 75420
29 + 75391 = 75420
31 + 75389 = 75420
43 + 75377 = 75420
53 + 75367 = 75420
67 + 75353 = 75420

Showing the first eight; more decompositions exist.
