Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51456, here are decompositions:

7 + 51449 = 51456
17 + 51439 = 51456
19 + 51437 = 51456
29 + 51427 = 51456
37 + 51419 = 51456
43 + 51413 = 51456
73 + 51383 = 51456
107 + 51349 = 51456

Showing the first eight; more decompositions exist.
