Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51908, here are decompositions:

37 + 51871 = 51908
79 + 51829 = 51908
139 + 51769 = 51908
229 + 51679 = 51908
271 + 51637 = 51908
277 + 51631 = 51908
331 + 51577 = 51908
397 + 51511 = 51908

Showing the first eight; more decompositions exist.
