Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51242, here are decompositions:

3 + 51239 = 51242
13 + 51229 = 51242
43 + 51199 = 51242
73 + 51169 = 51242
109 + 51133 = 51242
181 + 51061 = 51242
199 + 51043 = 51242
211 + 51031 = 51242

Showing the first eight; more decompositions exist.
