Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8610428, here are decompositions:

19 + 8610409 = 8610428
61 + 8610367 = 8610428
97 + 8610331 = 8610428
109 + 8610319 = 8610428
181 + 8610247 = 8610428
199 + 8610229 = 8610428
367 + 8610061 = 8610428
709 + 8609719 = 8610428

Showing the first eight; more decompositions exist.
