Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723586, here are decompositions:

17 + 8723569 = 8723586
89 + 8723497 = 8723586
103 + 8723483 = 8723586
107 + 8723479 = 8723586
127 + 8723459 = 8723586
149 + 8723437 = 8723586
163 + 8723423 = 8723586
167 + 8723419 = 8723586

Showing the first eight; more decompositions exist.
