Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051378, here are decompositions:

5 + 1051373 = 1051378
59 + 1051319 = 1051378
101 + 1051277 = 1051378
131 + 1051247 = 1051378
197 + 1051181 = 1051378
227 + 1051151 = 1051378
239 + 1051139 = 1051378
359 + 1051019 = 1051378

Showing the first eight; more decompositions exist.
