Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8591780, here are decompositions:

7 + 8591773 = 8591780
97 + 8591683 = 8591780
157 + 8591623 = 8591780
163 + 8591617 = 8591780
181 + 8591599 = 8591780
193 + 8591587 = 8591780
313 + 8591467 = 8591780
331 + 8591449 = 8591780

Showing the first eight; more decompositions exist.
