Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8736440, here are decompositions:

7 + 8736433 = 8736440
73 + 8736367 = 8736440
241 + 8736199 = 8736440
313 + 8736127 = 8736440
331 + 8736109 = 8736440
367 + 8736073 = 8736440
379 + 8736061 = 8736440
439 + 8736001 = 8736440

Showing the first eight; more decompositions exist.
