Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725458, here are decompositions:

29 + 8725429 = 8725458
37 + 8725421 = 8725458
59 + 8725399 = 8725458
61 + 8725397 = 8725458
67 + 8725391 = 8725458
97 + 8725361 = 8725458
101 + 8725357 = 8725458
139 + 8725319 = 8725458

Showing the first eight; more decompositions exist.
