Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700430, here are decompositions:

23 + 8700407 = 8700430
29 + 8700401 = 8700430
47 + 8700383 = 8700430
131 + 8700299 = 8700430
149 + 8700281 = 8700430
173 + 8700257 = 8700430
191 + 8700239 = 8700430
269 + 8700161 = 8700430

Showing the first eight; more decompositions exist.
