Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8706438, here are decompositions:

19 + 8706419 = 8706438
31 + 8706407 = 8706438
61 + 8706377 = 8706438
71 + 8706367 = 8706438
89 + 8706349 = 8706438
101 + 8706337 = 8706438
149 + 8706289 = 8706438
151 + 8706287 = 8706438

Showing the first eight; more decompositions exist.
