Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019738, here are decompositions:

7 + 1019731 = 1019738
37 + 1019701 = 1019738
229 + 1019509 = 1019738
271 + 1019467 = 1019738
409 + 1019329 = 1019738
457 + 1019281 = 1019738
487 + 1019251 = 1019738
541 + 1019197 = 1019738

Showing the first eight; more decompositions exist.
