Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690442, here are decompositions:

29 + 8690413 = 8690442
31 + 8690411 = 8690442
43 + 8690399 = 8690442
71 + 8690371 = 8690442
83 + 8690359 = 8690442
109 + 8690333 = 8690442
139 + 8690303 = 8690442
149 + 8690293 = 8690442

Showing the first eight; more decompositions exist.
