Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723784, here are decompositions:

53 + 8723731 = 8723784
107 + 8723677 = 8723784
131 + 8723653 = 8723784
191 + 8723593 = 8723784
233 + 8723551 = 8723784
263 + 8723521 = 8723784
347 + 8723437 = 8723784
397 + 8723387 = 8723784

Showing the first eight; more decompositions exist.
