Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619998, here are decompositions:

61 + 8619937 = 8619998
139 + 8619859 = 8619998
181 + 8619817 = 8619998
337 + 8619661 = 8619998
349 + 8619649 = 8619998
397 + 8619601 = 8619998
487 + 8619511 = 8619998
571 + 8619427 = 8619998

Showing the first eight; more decompositions exist.
