Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51172, here are decompositions:

3 + 51169 = 51172
41 + 51131 = 51172
101 + 51071 = 51172
113 + 51059 = 51172
179 + 50993 = 51172
263 + 50909 = 51172
281 + 50891 = 51172
383 + 50789 = 51172

Showing the first eight; more decompositions exist.
