Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1012378, here are decompositions:

5 + 1012373 = 1012378
71 + 1012307 = 1012378
89 + 1012289 = 1012378
137 + 1012241 = 1012378
149 + 1012229 = 1012378
281 + 1012097 = 1012378
347 + 1012031 = 1012378
431 + 1011947 = 1012378

Showing the first eight; more decompositions exist.
