Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51442, here are decompositions:

3 + 51439 = 51442
5 + 51437 = 51442
11 + 51431 = 51442
23 + 51419 = 51442
29 + 51413 = 51442
59 + 51383 = 51442
101 + 51341 = 51442
113 + 51329 = 51442

Showing the first eight; more decompositions exist.
