Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738998, here are decompositions:

41 + 8738957 = 8738998
197 + 8738801 = 8738998
239 + 8738759 = 8738998
269 + 8738729 = 8738998
419 + 8738579 = 8738998
431 + 8738567 = 8738998
491 + 8738507 = 8738998
599 + 8738399 = 8738998

Showing the first eight; more decompositions exist.
