Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728426, here are decompositions:

29 + 8728397 = 8728426
53 + 8728373 = 8728426
137 + 8728289 = 8728426
233 + 8728193 = 8728426
257 + 8728169 = 8728426
347 + 8728079 = 8728426
353 + 8728073 = 8728426
389 + 8728037 = 8728426

Showing the first eight; more decompositions exist.
