Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723182, here are decompositions:

59 + 8723123 = 8723182
101 + 8723081 = 8723182
191 + 8722991 = 8723182
233 + 8722949 = 8723182
269 + 8722913 = 8723182
353 + 8722829 = 8723182
383 + 8722799 = 8723182
443 + 8722739 = 8723182

Showing the first eight; more decompositions exist.
