Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724136, here are decompositions:

149 + 8723987 = 8724136
227 + 8723909 = 8724136
233 + 8723903 = 8724136
257 + 8723879 = 8724136
347 + 8723789 = 8724136
653 + 8723483 = 8724136
677 + 8723459 = 8724136
1013 + 8723123 = 8724136

Showing the first eight; more decompositions exist.
