Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8708580, here are decompositions:

43 + 8708537 = 8708580
53 + 8708527 = 8708580
59 + 8708521 = 8708580
61 + 8708519 = 8708580
71 + 8708509 = 8708580
73 + 8708507 = 8708580
79 + 8708501 = 8708580
131 + 8708449 = 8708580

Showing the first eight; more decompositions exist.
