Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8662990, here are decompositions:

3 + 8662987 = 8662990
47 + 8662943 = 8662990
101 + 8662889 = 8662990
131 + 8662859 = 8662990
137 + 8662853 = 8662990
179 + 8662811 = 8662990
191 + 8662799 = 8662990
239 + 8662751 = 8662990

Showing the first eight; more decompositions exist.
