Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619842, here are decompositions:

31 + 8619811 = 8619842
181 + 8619661 = 8619842
193 + 8619649 = 8619842
241 + 8619601 = 8619842
331 + 8619511 = 8619842
373 + 8619469 = 8619842
409 + 8619433 = 8619842
421 + 8619421 = 8619842

Showing the first eight; more decompositions exist.
