Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8736458, here are decompositions:

271 + 8736187 = 8736458
331 + 8736127 = 8736458
349 + 8736109 = 8736458
397 + 8736061 = 8736458
421 + 8736037 = 8736458
457 + 8736001 = 8736458
487 + 8735971 = 8736458
607 + 8735851 = 8736458

Showing the first eight; more decompositions exist.
