Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8597642, here are decompositions:

3 + 8597639 = 8597642
13 + 8597629 = 8597642
19 + 8597623 = 8597642
43 + 8597599 = 8597642
271 + 8597371 = 8597642
349 + 8597293 = 8597642
379 + 8597263 = 8597642
439 + 8597203 = 8597642

Showing the first eight; more decompositions exist.
