Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042772, here are decompositions:

13 + 1042759 = 1042772
79 + 1042693 = 1042772
139 + 1042633 = 1042772
163 + 1042609 = 1042772
373 + 1042399 = 1042772
439 + 1042333 = 1042772
463 + 1042309 = 1042772
499 + 1042273 = 1042772

Showing the first eight; more decompositions exist.
