Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51446, here are decompositions:

7 + 51439 = 51446
19 + 51427 = 51446
97 + 51349 = 51446
103 + 51343 = 51446
139 + 51307 = 51446
163 + 51283 = 51446
229 + 51217 = 51446
277 + 51169 = 51446

Showing the first eight; more decompositions exist.
