Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51362, here are decompositions:

13 + 51349 = 51362
19 + 51343 = 51362
79 + 51283 = 51362
163 + 51199 = 51362
193 + 51169 = 51362
211 + 51151 = 51362
229 + 51133 = 51362
331 + 51031 = 51362

Showing the first eight; more decompositions exist.
