Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749526, here are decompositions:

103 + 8749423 = 8749526
109 + 8749417 = 8749526
283 + 8749243 = 8749526
307 + 8749219 = 8749526
439 + 8749087 = 8749526
547 + 8748979 = 8749526
673 + 8748853 = 8749526
739 + 8748787 = 8749526

Showing the first eight; more decompositions exist.
