Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988042, here are decompositions:

59 + 987983 = 988042
71 + 987971 = 988042
101 + 987941 = 988042
113 + 987929 = 988042
131 + 987911 = 988042
173 + 987869 = 988042
191 + 987851 = 988042
233 + 987809 = 988042

Showing the first eight; more decompositions exist.
