Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723186, here are decompositions:

37 + 8723149 = 8723186
79 + 8723107 = 8723186
97 + 8723089 = 8723186
139 + 8723047 = 8723186
193 + 8722993 = 8723186
397 + 8722789 = 8723186
709 + 8722477 = 8723186
727 + 8722459 = 8723186

Showing the first eight; more decompositions exist.
