Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8736940, here are decompositions:

29 + 8736911 = 8736940
41 + 8736899 = 8736940
59 + 8736881 = 8736940
131 + 8736809 = 8736940
239 + 8736701 = 8736940
257 + 8736683 = 8736940
281 + 8736659 = 8736940
293 + 8736647 = 8736940

Showing the first eight; more decompositions exist.
