Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8733990, here are decompositions:

11 + 8733979 = 8733990
61 + 8733929 = 8733990
101 + 8733889 = 8733990
151 + 8733839 = 8733990
157 + 8733833 = 8733990
163 + 8733827 = 8733990
179 + 8733811 = 8733990
271 + 8733719 = 8733990

Showing the first eight; more decompositions exist.
