Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990358, here are decompositions:

29 + 990329 = 990358
71 + 990287 = 990358
179 + 990179 = 990358
359 + 989999 = 990358
419 + 989939 = 990358
449 + 989909 = 990358
521 + 989837 = 990358
797 + 989561 = 990358

Showing the first eight; more decompositions exist.
