Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1252, here are decompositions:

3 + 1249 = 1252
23 + 1229 = 1252
29 + 1223 = 1252
59 + 1193 = 1252
71 + 1181 = 1252
89 + 1163 = 1252
101 + 1151 = 1252
149 + 1103 = 1252

Showing the first eight; more decompositions exist.
