Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723774, here are decompositions:

43 + 8723731 = 8723774
67 + 8723707 = 8723774
97 + 8723677 = 8723774
181 + 8723593 = 8723774
223 + 8723551 = 8723774
277 + 8723497 = 8723774
337 + 8723437 = 8723774
421 + 8723353 = 8723774

Showing the first eight; more decompositions exist.
