Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8610990, here are decompositions:

29 + 8610961 = 8610990
53 + 8610937 = 8610990
71 + 8610919 = 8610990
97 + 8610893 = 8610990
109 + 8610881 = 8610990
127 + 8610863 = 8610990
139 + 8610851 = 8610990
163 + 8610827 = 8610990

Showing the first eight; more decompositions exist.
