Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10380, here are decompositions:

11 + 10369 = 10380
23 + 10357 = 10380
37 + 10343 = 10380
43 + 10337 = 10380
47 + 10333 = 10380
59 + 10321 = 10380
67 + 10313 = 10380
79 + 10301 = 10380

Showing the first eight; more decompositions exist.
