Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51420, here are decompositions:

7 + 51413 = 51420
13 + 51407 = 51420
37 + 51383 = 51420
59 + 51361 = 51420
71 + 51349 = 51420
73 + 51347 = 51420
79 + 51341 = 51420
113 + 51307 = 51420

Showing the first eight; more decompositions exist.
