Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620244, here are decompositions:

13 + 8620231 = 8620244
103 + 8620141 = 8620244
181 + 8620063 = 8620244
307 + 8619937 = 8620244
433 + 8619811 = 8620244
643 + 8619601 = 8620244
733 + 8619511 = 8620244
811 + 8619433 = 8620244

Showing the first eight; more decompositions exist.
