Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51812, here are decompositions:

43 + 51769 = 51812
139 + 51673 = 51812
181 + 51631 = 51812
199 + 51613 = 51812
331 + 51481 = 51812
373 + 51439 = 51812
463 + 51349 = 51812
571 + 51241 = 51812

Showing the first eight; more decompositions exist.
