Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680844, here are decompositions:

31 + 8680813 = 8680844
43 + 8680801 = 8680844
103 + 8680741 = 8680844
127 + 8680717 = 8680844
331 + 8680513 = 8680844
373 + 8680471 = 8680844
541 + 8680303 = 8680844
547 + 8680297 = 8680844

Showing the first eight; more decompositions exist.
