Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51338, here are decompositions:

31 + 51307 = 51338
97 + 51241 = 51338
109 + 51229 = 51338
139 + 51199 = 51338
181 + 51157 = 51338
229 + 51109 = 51338
277 + 51061 = 51338
307 + 51031 = 51338

Showing the first eight; more decompositions exist.
