Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723742, here are decompositions:

11 + 8723731 = 8723742
89 + 8723653 = 8723742
103 + 8723639 = 8723742
149 + 8723593 = 8723742
173 + 8723569 = 8723742
191 + 8723551 = 8723742
211 + 8723531 = 8723742
263 + 8723479 = 8723742

Showing the first eight; more decompositions exist.
