Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8597780, here are decompositions:

43 + 8597737 = 8597780
73 + 8597707 = 8597780
97 + 8597683 = 8597780
151 + 8597629 = 8597780
157 + 8597623 = 8597780
181 + 8597599 = 8597780
193 + 8597587 = 8597780
229 + 8597551 = 8597780

Showing the first eight; more decompositions exist.
