Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990112, here are decompositions:

59 + 990053 = 990112
89 + 990023 = 990112
113 + 989999 = 990112
131 + 989981 = 990112
173 + 989939 = 990112
191 + 989921 = 990112
239 + 989873 = 990112
281 + 989831 = 990112

Showing the first eight; more decompositions exist.
