Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51426, here are decompositions:

5 + 51421 = 51426
7 + 51419 = 51426
13 + 51413 = 51426
19 + 51407 = 51426
43 + 51383 = 51426
79 + 51347 = 51426
83 + 51343 = 51426
97 + 51329 = 51426

Showing the first eight; more decompositions exist.
