Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990160, here are decompositions:

23 + 990137 = 990160
107 + 990053 = 990160
137 + 990023 = 990160
179 + 989981 = 990160
239 + 989921 = 990160
251 + 989909 = 990160
383 + 989777 = 990160
599 + 989561 = 990160

Showing the first eight; more decompositions exist.
