Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726620, here are decompositions:

47 + 8726573 = 8726620
113 + 8726507 = 8726620
173 + 8726447 = 8726620
239 + 8726381 = 8726620
257 + 8726363 = 8726620
263 + 8726357 = 8726620
269 + 8726351 = 8726620
347 + 8726273 = 8726620

Showing the first eight; more decompositions exist.
