Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700438, here are decompositions:

7 + 8700431 = 8700438
17 + 8700421 = 8700438
31 + 8700407 = 8700438
37 + 8700401 = 8700438
139 + 8700299 = 8700438
151 + 8700287 = 8700438
157 + 8700281 = 8700438
181 + 8700257 = 8700438

Showing the first eight; more decompositions exist.
