Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1000378, here are decompositions:

11 + 1000367 = 1000378
89 + 1000289 = 1000378
167 + 1000211 = 1000378
179 + 1000199 = 1000378
191 + 1000187 = 1000378
227 + 1000151 = 1000378
257 + 1000121 = 1000378
419 + 999959 = 1000378

Showing the first eight; more decompositions exist.
