Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989912, here are decompositions:

3 + 989909 = 989912
43 + 989869 = 989912
73 + 989839 = 989912
109 + 989803 = 989912
151 + 989761 = 989912
163 + 989749 = 989912
193 + 989719 = 989912
241 + 989671 = 989912

Showing the first eight; more decompositions exist.
