Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671580, here are decompositions:

7 + 8671573 = 8671580
31 + 8671549 = 8671580
61 + 8671519 = 8671580
79 + 8671501 = 8671580
109 + 8671471 = 8671580
139 + 8671441 = 8671580
199 + 8671381 = 8671580
241 + 8671339 = 8671580

Showing the first eight; more decompositions exist.
