Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8664442, here are decompositions:

11 + 8664431 = 8664442
23 + 8664419 = 8664442
29 + 8664413 = 8664442
53 + 8664389 = 8664442
113 + 8664329 = 8664442
131 + 8664311 = 8664442
389 + 8664053 = 8664442
419 + 8664023 = 8664442

Showing the first eight; more decompositions exist.
