Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8753990, here are decompositions:

13 + 8753977 = 8753990
19 + 8753971 = 8753990
43 + 8753947 = 8753990
97 + 8753893 = 8753990
103 + 8753887 = 8753990
151 + 8753839 = 8753990
181 + 8753809 = 8753990
199 + 8753791 = 8753990

Showing the first eight; more decompositions exist.
