Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990132, here are decompositions:

79 + 990053 = 990132
89 + 990043 = 990132
109 + 990023 = 990132
131 + 990001 = 990132
151 + 989981 = 990132
173 + 989959 = 990132
181 + 989951 = 990132
193 + 989939 = 990132

Showing the first eight; more decompositions exist.
