Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8610442, here are decompositions:

11 + 8610431 = 8610442
53 + 8610389 = 8610442
83 + 8610359 = 8610442
101 + 8610341 = 8610442
131 + 8610311 = 8610442
149 + 8610293 = 8610442
173 + 8610269 = 8610442
233 + 8610209 = 8610442

Showing the first eight; more decompositions exist.
