Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988850, here are decompositions:

13 + 988837 = 988850
61 + 988789 = 988850
67 + 988783 = 988850
139 + 988711 = 988850
157 + 988693 = 988850
199 + 988651 = 988850
271 + 988579 = 988850
349 + 988501 = 988850

Showing the first eight; more decompositions exist.
