Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1376, here are decompositions:

3 + 1373 = 1376
73 + 1303 = 1376
79 + 1297 = 1376
97 + 1279 = 1376
127 + 1249 = 1376
139 + 1237 = 1376
163 + 1213 = 1376
223 + 1153 = 1376

Showing the first eight; more decompositions exist.
