Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019492, here are decompositions:

13 + 1019479 = 1019492
43 + 1019449 = 1019492
79 + 1019413 = 1019492
139 + 1019353 = 1019492
163 + 1019329 = 1019492
211 + 1019281 = 1019492
241 + 1019251 = 1019492
283 + 1019209 = 1019492

Showing the first eight; more decompositions exist.
