Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989042, here are decompositions:

13 + 989029 = 989042
31 + 989011 = 989042
79 + 988963 = 989042
181 + 988861 = 989042
193 + 988849 = 989042
283 + 988759 = 989042
331 + 988711 = 989042
349 + 988693 = 989042

Showing the first eight; more decompositions exist.
