Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726436, here are decompositions:

53 + 8726383 = 8726436
73 + 8726363 = 8726436
79 + 8726357 = 8726436
107 + 8726329 = 8726436
113 + 8726323 = 8726436
163 + 8726273 = 8726436
179 + 8726257 = 8726436
193 + 8726243 = 8726436

Showing the first eight; more decompositions exist.
