Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019312, here are decompositions:

31 + 1019281 = 1019312
61 + 1019251 = 1019312
103 + 1019209 = 1019312
139 + 1019173 = 1019312
193 + 1019119 = 1019312
241 + 1019071 = 1019312
313 + 1018999 = 1019312
331 + 1018981 = 1019312

Showing the first eight; more decompositions exist.
