Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725582, here are decompositions:

11 + 8725571 = 8725582
59 + 8725523 = 8725582
71 + 8725511 = 8725582
83 + 8725499 = 8725582
101 + 8725481 = 8725582
191 + 8725391 = 8725582
263 + 8725319 = 8725582
443 + 8725139 = 8725582

Showing the first eight; more decompositions exist.
