Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723744, here are decompositions:

13 + 8723731 = 8723744
37 + 8723707 = 8723744
67 + 8723677 = 8723744
151 + 8723593 = 8723744
193 + 8723551 = 8723744
223 + 8723521 = 8723744
307 + 8723437 = 8723744
397 + 8723347 = 8723744

Showing the first eight; more decompositions exist.
