Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723772, here are decompositions:

41 + 8723731 = 8723772
163 + 8723609 = 8723772
179 + 8723593 = 8723772
241 + 8723531 = 8723772
251 + 8723521 = 8723772
293 + 8723479 = 8723772
313 + 8723459 = 8723772
331 + 8723441 = 8723772

Showing the first eight; more decompositions exist.
