Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019650, here are decompositions:

3 + 1019647 = 1019650
11 + 1019639 = 1019650
101 + 1019549 = 1019650
113 + 1019537 = 1019650
179 + 1019471 = 1019650
197 + 1019453 = 1019650
227 + 1019423 = 1019650
239 + 1019411 = 1019650

Showing the first eight; more decompositions exist.
