Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51432, here are decompositions:

5 + 51427 = 51432
11 + 51421 = 51432
13 + 51419 = 51432
19 + 51413 = 51432
71 + 51361 = 51432
83 + 51349 = 51432
89 + 51343 = 51432
103 + 51329 = 51432

Showing the first eight; more decompositions exist.
