Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749038, here are decompositions:

19 + 8749019 = 8749038
31 + 8749007 = 8749038
37 + 8749001 = 8749038
47 + 8748991 = 8749038
59 + 8748979 = 8749038
149 + 8748889 = 8749038
157 + 8748881 = 8749038
191 + 8748847 = 8749038

Showing the first eight; more decompositions exist.
