Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726404, here are decompositions:

3 + 8726401 = 8726404
23 + 8726381 = 8726404
41 + 8726363 = 8726404
47 + 8726357 = 8726404
53 + 8726351 = 8726404
131 + 8726273 = 8726404
263 + 8726141 = 8726404
311 + 8726093 = 8726404

Showing the first eight; more decompositions exist.
