Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681126, here are decompositions:

37 + 8681089 = 8681126
67 + 8681059 = 8681126
79 + 8681047 = 8681126
313 + 8680813 = 8681126
373 + 8680753 = 8681126
409 + 8680717 = 8681126
457 + 8680669 = 8681126
613 + 8680513 = 8681126

Showing the first eight; more decompositions exist.
