Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8736438, here are decompositions:

5 + 8736433 = 8736438
37 + 8736401 = 8736438
71 + 8736367 = 8736438
97 + 8736341 = 8736438
229 + 8736209 = 8736438
239 + 8736199 = 8736438
251 + 8736187 = 8736438
311 + 8736127 = 8736438

Showing the first eight; more decompositions exist.
