Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660408, here are decompositions:

7 + 8660401 = 8660408
139 + 8660269 = 8660408
181 + 8660227 = 8660408
331 + 8660077 = 8660408
409 + 8659999 = 8660408
487 + 8659921 = 8660408
499 + 8659909 = 8660408
541 + 8659867 = 8660408

Showing the first eight; more decompositions exist.
