Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1011380, here are decompositions:

3 + 1011377 = 1011380
31 + 1011349 = 1011380
37 + 1011343 = 1011380
103 + 1011277 = 1011380
109 + 1011271 = 1011380
151 + 1011229 = 1011380
163 + 1011217 = 1011380
241 + 1011139 = 1011380

Showing the first eight; more decompositions exist.
