Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719838, here are decompositions:

7 + 8719831 = 8719838
19 + 8719819 = 8719838
37 + 8719801 = 8719838
67 + 8719771 = 8719838
139 + 8719699 = 8719838
157 + 8719681 = 8719838
271 + 8719567 = 8719838
397 + 8719441 = 8719838

Showing the first eight; more decompositions exist.
