Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51382, here are decompositions:

41 + 51341 = 51382
53 + 51329 = 51382
179 + 51203 = 51382
251 + 51131 = 51382
311 + 51071 = 51382
389 + 50993 = 51382
431 + 50951 = 51382
491 + 50891 = 51382

Showing the first eight; more decompositions exist.
