Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025378, here are decompositions:

31 + 1025347 = 1025378
97 + 1025281 = 1025378
139 + 1025239 = 1025378
181 + 1025197 = 1025378
229 + 1025149 = 1025378
241 + 1025137 = 1025378
331 + 1025047 = 1025378
349 + 1025029 = 1025378

Showing the first eight; more decompositions exist.
