Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726432, here are decompositions:

31 + 8726401 = 8726432
73 + 8726359 = 8726432
103 + 8726329 = 8726432
109 + 8726323 = 8726432
193 + 8726239 = 8726432
223 + 8726209 = 8726432
229 + 8726203 = 8726432
331 + 8726101 = 8726432

Showing the first eight; more decompositions exist.
