Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8609408, here are decompositions:

37 + 8609371 = 8609408
61 + 8609347 = 8609408
127 + 8609281 = 8609408
139 + 8609269 = 8609408
151 + 8609257 = 8609408
271 + 8609137 = 8609408
331 + 8609077 = 8609408
499 + 8608909 = 8609408

Showing the first eight; more decompositions exist.
