Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8665408, here are decompositions:

47 + 8665361 = 8665408
131 + 8665277 = 8665408
149 + 8665259 = 8665408
251 + 8665157 = 8665408
431 + 8664977 = 8665408
449 + 8664959 = 8665408
461 + 8664947 = 8665408
467 + 8664941 = 8665408

Showing the first eight; more decompositions exist.
