Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51444, here are decompositions:

5 + 51439 = 51444
7 + 51437 = 51444
13 + 51431 = 51444
17 + 51427 = 51444
23 + 51421 = 51444
31 + 51413 = 51444
37 + 51407 = 51444
61 + 51383 = 51444

Showing the first eight; more decompositions exist.
