Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680572, here are decompositions:

13 + 8680559 = 8680572
29 + 8680543 = 8680572
59 + 8680513 = 8680572
71 + 8680501 = 8680572
101 + 8680471 = 8680572
163 + 8680409 = 8680572
181 + 8680391 = 8680572
193 + 8680379 = 8680572

Showing the first eight; more decompositions exist.
