Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009790, here are decompositions:

3 + 1009787 = 1009790
43 + 1009747 = 1009790
139 + 1009651 = 1009790
163 + 1009627 = 1009790
181 + 1009609 = 1009790
283 + 1009507 = 1009790
307 + 1009483 = 1009790
373 + 1009417 = 1009790

Showing the first eight; more decompositions exist.
