Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749406, here are decompositions:

97 + 8749309 = 8749406
163 + 8749243 = 8749406
199 + 8749207 = 8749406
433 + 8748973 = 8749406
619 + 8748787 = 8749406
733 + 8748673 = 8749406
823 + 8748583 = 8749406
907 + 8748499 = 8749406

Showing the first eight; more decompositions exist.
