Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101380, here are decompositions:

3 + 101377 = 101380
17 + 101363 = 101380
47 + 101333 = 101380
101 + 101279 = 101380
107 + 101273 = 101380
113 + 101267 = 101380
173 + 101207 = 101380
197 + 101183 = 101380

Showing the first eight; more decompositions exist.
