Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51478, here are decompositions:

5 + 51473 = 51478
17 + 51461 = 51478
29 + 51449 = 51478
41 + 51437 = 51478
47 + 51431 = 51478
59 + 51419 = 51478
71 + 51407 = 51478
131 + 51347 = 51478

Showing the first eight; more decompositions exist.
