Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51438, here are decompositions:

7 + 51431 = 51438
11 + 51427 = 51438
17 + 51421 = 51438
19 + 51419 = 51438
31 + 51407 = 51438
89 + 51349 = 51438
97 + 51341 = 51438
109 + 51329 = 51438

Showing the first eight; more decompositions exist.
