Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51230, here are decompositions:

13 + 51217 = 51230
31 + 51199 = 51230
37 + 51193 = 51230
61 + 51169 = 51230
73 + 51157 = 51230
79 + 51151 = 51230
97 + 51133 = 51230
199 + 51031 = 51230

Showing the first eight; more decompositions exist.
