Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725426, here are decompositions:

5 + 8725421 = 8725426
29 + 8725397 = 8725426
107 + 8725319 = 8725426
173 + 8725253 = 8725426
293 + 8725133 = 8725426
389 + 8725037 = 8725426
443 + 8724983 = 8725426
599 + 8724827 = 8725426

Showing the first eight; more decompositions exist.
