Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51290, here are decompositions:

3 + 51287 = 51290
7 + 51283 = 51290
61 + 51229 = 51290
73 + 51217 = 51290
97 + 51193 = 51290
139 + 51151 = 51290
157 + 51133 = 51290
181 + 51109 = 51290

Showing the first eight; more decompositions exist.
