Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1016870, here are decompositions:

31 + 1016839 = 1016870
97 + 1016773 = 1016870
139 + 1016731 = 1016870
181 + 1016689 = 1016870
229 + 1016641 = 1016870
271 + 1016599 = 1016870
373 + 1016497 = 1016870
499 + 1016371 = 1016870

Showing the first eight; more decompositions exist.
