Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51430, here are decompositions:

3 + 51427 = 51430
11 + 51419 = 51430
17 + 51413 = 51430
23 + 51407 = 51430
47 + 51383 = 51430
83 + 51347 = 51430
89 + 51341 = 51430
101 + 51329 = 51430

Showing the first eight; more decompositions exist.
