Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701438, here are decompositions:

29 + 8701409 = 8701438
47 + 8701391 = 8701438
71 + 8701367 = 8701438
89 + 8701349 = 8701438
149 + 8701289 = 8701438
167 + 8701271 = 8701438
227 + 8701211 = 8701438
491 + 8700947 = 8701438

Showing the first eight; more decompositions exist.
