Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019930, here are decompositions:

3 + 1019927 = 1019930
31 + 1019899 = 1019930
73 + 1019857 = 1019930
103 + 1019827 = 1019930
199 + 1019731 = 1019930
229 + 1019701 = 1019930
283 + 1019647 = 1019930
313 + 1019617 = 1019930

Showing the first eight; more decompositions exist.
