Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723190, here are decompositions:

41 + 8723149 = 8723190
53 + 8723137 = 8723190
67 + 8723123 = 8723190
83 + 8723107 = 8723190
101 + 8723089 = 8723190
109 + 8723081 = 8723190
127 + 8723063 = 8723190
137 + 8723053 = 8723190

Showing the first eight; more decompositions exist.
