Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726580, here are decompositions:

7 + 8726573 = 8726580
11 + 8726569 = 8726580
47 + 8726533 = 8726580
53 + 8726527 = 8726580
59 + 8726521 = 8726580
73 + 8726507 = 8726580
101 + 8726479 = 8726580
113 + 8726467 = 8726580

Showing the first eight; more decompositions exist.
