Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725590, here are decompositions:

19 + 8725571 = 8725590
23 + 8725567 = 8725590
43 + 8725547 = 8725590
59 + 8725531 = 8725590
67 + 8725523 = 8725590
79 + 8725511 = 8725590
101 + 8725489 = 8725590
109 + 8725481 = 8725590

Showing the first eight; more decompositions exist.
