Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629844, here are decompositions:

31 + 8629813 = 8629844
73 + 8629771 = 8629844
163 + 8629681 = 8629844
193 + 8629651 = 8629844
283 + 8629561 = 8629844
337 + 8629507 = 8629844
397 + 8629447 = 8629844
547 + 8629297 = 8629844

Showing the first eight; more decompositions exist.
