Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8597990, here are decompositions:

13 + 8597977 = 8597990
43 + 8597947 = 8597990
127 + 8597863 = 8597990
151 + 8597839 = 8597990
283 + 8597707 = 8597990
307 + 8597683 = 8597990
367 + 8597623 = 8597990
439 + 8597551 = 8597990

Showing the first eight; more decompositions exist.
