Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8736490, here are decompositions:

17 + 8736473 = 8736490
29 + 8736461 = 8736490
41 + 8736449 = 8736490
89 + 8736401 = 8736490
149 + 8736341 = 8736490
167 + 8736323 = 8736490
227 + 8736263 = 8736490
281 + 8736209 = 8736490

Showing the first eight; more decompositions exist.
