Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990044, here are decompositions:

7 + 990037 = 990044
31 + 990013 = 990044
43 + 990001 = 990044
67 + 989977 = 990044
73 + 989971 = 990044
127 + 989917 = 990044
157 + 989887 = 990044
241 + 989803 = 990044

Showing the first eight; more decompositions exist.
